Technically, none. If a scale has sharps then it won't have flats and vice-versa. But, in this case it's a matter of semantics: A flat is the same as G sharp and there are several scales that have both G sharp and C sharp - for example, D major, A major, E major, B major, F# major, C# major, G# major, B minor, F# minor, C# minor, G# minor - and then there are the other 5 modes besides major and minor.
As well, C# is the same as D flat. D flat and A flat are also found in several scales.
C, C sharp/D flat, D, D sharp/E flat, E, F, F sharp/G flat, G, G sharp/A flat, A, A sharp/B flat, B, C.
it has a C sharp but no D natural
The dominant (fifth) degree of a D sharp major scale is A sharp.
The C major scale and its relative minor, the A minor scale. C Major.
No. There are a (plus a flat and a sharp), b (plus b flat and b sharp), c (flat and sharp), d (flat and sharp), e (flat and sharp), f (flat and sharp), and g (flat and sharp). That makes a, b, c, d, e, f, g Plus the flat and sharp for each, making 21 notes of the scale.
D flat, E flat, F flat, G Flat, A flat, B Double flat, C flat, D flat. However, since D flat and C sharp are, essentially, the same, it would be easier to write in terms of C sharp. The scale would then read C sharp, D sharp, E, F sharp, G sharp, A, B, C sharp.
There are different rules. For major keys, the rule is this (by the way, # means sharp): C major scale- 0 sharps or flats G major scale- 1 sharp - F sharp D major scale- 2 sharps - F and C sharp A major scale- 3 sharps - F, C, G sharp E major scale- 4 sharps - F, C, G, D sharp B major scale- 5 sharps - F, C, G, D, A sharp F# major scale- 6 sharps - F, C, G, D, A, E sharp C# major scale - 7 sharps - F, C, G, D, A, E, B sharp. For major keys with flats: F major scale - 1 flat - B flat B flat major scale - 2 flats - B, E flat E flat major scale - 3 flats - B, E, A flat A flat major scale - 4 flats - B, E, A, D flat D flat major scale - 5 flats - B, E, A, D, G flat G flat major scale - 6 flats - B, E, A, D, G, C flat C flat major scale - 7 flats - B, E, A, D, G, C, F flat So as you might have noticed, in increasing order of sharps it is: F, C, G, D, A, E, B. And the increasing order of flats is B, E, A, D, G, C, F. If you notice the order of sharps is the opposite of the order of flats.
Firstly, lets think about your major cghords. All major chord consist of the first (root) third and fifth notes of the major scale from which they come. so, for c major for eg, C E and G. you chords will all contain 1st 3rd and 5th notes somwhere. so, to make them minor, simply lower the third by a semitone, ie one fret, and hey presto, a minor chord.

D minor - more specifically, D harmonic minor (the version of the minor scale with a flat 6 and a sharp 7). However, you will never see a key signature with a B flat and a C sharp. The key signature will only contain B flat.
UP: d sharp e sharp f sharp g sharp a sharp b sharp c double-sharp d sharp DOWN: d sharp c sharp b natural a sharp g sharp f sharp e sharp d sharp
The scale of 'C' - it uses neither sharp or flat notes.
In theory it is impossible for a scale to have but a flat and a sharp but if it is in inharmonics then yes it is possible to have a flat and a sharp just depends on how you look at it.
