First it would depend on the number of double-sharps in the key signature. Since any fewer than 7 double-sharps in the key signature would create a mode other than major or the natural minor, we would have to begin with 7 double-sharps. This would effectively raise every note in the C Major scale up one whole step giving us C double-sharp major. Note that this particular key signature would be impractical to read since C double-sharp Major is enharmonic with D Major which only has one sharp.
Enharmonics is the name for a pitch that is "spelled" three different ways. # C=B sharp, D double flat # D flat= C sharp, B double sharp....
Well, first off, there's the key signature. That's the sharps or flats at the *beginning* of the line of music. They dictate notes which should be sharp or flat *all the time*. So for instance, if the song is in the key of G, there will be a sharp sign at the beginningf every line of music, on the top line of the staff (assuming treble (G) clef), to indicate that F's are sharp. Always. So every time you see an F anywhere on the staff, it should be played as an F#, even though it won't be written as an F#; it will be just written as a normal F, and you're supposed to know from the key signature that it really means F#. In addition to the sharp or flat symbols, there's also the natural symbol. This means "*don't* play the note sharp or flat*. For instance, let's say there's a song in G, which has the key signature I just described, indicating F's are always sharp. But suppose that in one instance, it really wants a normal F, an F natural-- not an F#. The way that that gets indicated is by putting an explicit natural sign next to the note (instead of a sharp or flat). The natural sign looks like a square version of a combination lower-case b and lower-case q; that is, a little square box with a tail coming off down the right side, and another sticking up on the left side. Finally, there are the rarely seen *double* sharp and *double* flat. These indicate that a note that's *already* sharp should be made *even sharper*. For instance, again, in my key-of-G example, I could indicate an F-double-sharp, which would mean take your F# and raise it *another* half step. The resulting note would be identical to a G, of course, which is why it is seldom seen. You'd typically only ever see it in a rare key such as G#. If you were in the key of G#, then *every* note would be sharp, except for F's, which would need to be *double* sharped. You'd want to call that note F-double-sharp, rather than G, because you've already got G#; music theory dictates that you don't want your scale to have two kinds of G but no F's of any kind. That is, if you don't call it F-double-sharp, your scale would be: G# A# B# C# D# E# G G#. Two flavours of G, no flavours of F. We'd rather have one of every letter. So we name the notes G# A# B# C# D# E# Fx G#. A double sharp looks like a little X. A double flat simply looks like two flats right next to each other. Why they couldn't have just used two sharps next to each other for double-sharp is a mystery I can't answer.

A natural and a sharp before a note means that the note was previously a double-sharp and is now just a sharp.
A natural. If a natural is added before a note, then if that note is sharpened or flattened in the key signature, then for that one note that has the natural in front of it (and all of the rest of the same notes in the bar), it will not be sharpened or flattened. Eg. If I was composing a song in the key of D Major (F# and C# in the key signature) and I wanted a normal F (not sharp), then I would add a natural in front of it. And for the rest of the song, all of the Fs would still be sharpened.
It's an extremely rare scale. It's what you call an "imaginary key signature", one that is there in theory, but isn't all that practical -- seeing as you could just compose in F major. However... E# Major is a scale with 3 sharps (E, A, & B) and 4 double sharps (F, G, C, & D) in the key signature. [ The double sharp symbol loosely resembles a lowercase "x". ] So, the scale goes as follows: E sharp (E #), F double sharp (F x), G double sharp (G x), A sharp (A #), B sharp (B #), C double sharp (C x), D double sharp (D x), E sharp (E #) I hope this helped.
Yes, unless preceded by a Natural sign.
Sharps are the note one semitone higher than a given natural note, for example, D-sharp is one semitone higherthan D.Flats are the note one semitone lower than a given natural note, so D-flat is one semitone lower than D.Natural signs get rid of a previous sharp or flat in the same bar, or raises or lowers a sharp or flat already included in the key signature - e.g. the F-sharp in G major.Sharps and flats can be modified further too - resulting in a double sharp or double flat - which means that any double sharp or double flat will be a whole tone higher or lower than a given natural note, for example, D double-sharp would be the same key as E and D double-flat would be the same as C. Again a natural sign would get rid of the double flat or sharp.Sometimes natural keys have to be named as either sharp or flat, e.g. in C-sharp minor the seventh degree is B, but we have to raise B to B-sharp to create a C-sharp harmonic minor scale, which uses a raised seventh. Now we could call the B-sharp 'C' but that would not be correct as we need to use all letter names in a diatonic scale, and technically the C is functioning as a raised B in the key or C-sharp minor.

There is no key signature for D harmonic minor in particular - as the raised seventh is not part of the key signature. In all clefs, D minor has one flat and in all cases (since the raised seventh in this scale is C♯), to avoid confusion it is best to avoid having both a sharp and a flat in the same key signature.
Key signatures are the sharps or flats at the beginning of the staff. To identify the key signature of a scale that consists of all sharps, look at the last sharp in the key signature. Whichever note the last sharp lies on, the key of the scale is one note above it. To identify the key signature of a scale that consists of all flats, look at the note directly before the last flat in the key signature. The second-to-last note is the name of the key signature of flat keys. However, you cannot use this helpful trick with the F Major Scale which only has one flat (B flat).
G flat minor or F sharp minor. F♯, C♯, G♯, D♯, and A♯ minor all have a G♯ in their key signature.
A natural. If a natural is added before a note, then if that note is sharpened or flattened in the key signature, then for that one note that has the natural in front of it (and all of the rest of the same notes in the bar), it will not be sharpened or flattened. Eg. If I was composing a song in the key of D Major (F# and C# in the key signature) and I wanted a normal F (not sharp), then I would add a natural in front of it. And for the rest of the song, all of the Fs would still be sharpened.
An accidental is a sharp or flat that isn't in the key signature. For example, if your key signature says that all f's and c's are sharp, and then a G is sharped somewhere in the music, it would be an accidental.
