Anything beyond a double sharp exists only in theory and not in practice. A quintuple sharp would raise a note by 5 half steps, so a C with 5 sharps would sound the same as F.
Just as G sharp is one semitone above G, and G double sharp is two semitones above G, G quintuple sharp can be found five chromatic semitones--equal in twelve-tone equal temperament to a perfect fourth--above G natural. G quintuple sharp is enharmonic to A triple sharp, B sharp, and--most notably--C, as well as D double flat, E quadruple flat and F quintuple flat. On a piano, this note can be played by striking the white key immediately on the left of a pair of black keys. Triple sharps, triple flats, quadruple sharps and the such are very rarely encountered, and so the inability to play a quintuple sharp on the piano will not severely disadvantage one. Wherever did you come across this one?
F would be C quintuple sharp.
No
On a traditional piano with 88 notes, there is 36 black or "sharp" keys, and 52 white
Okay, there are 88 keys altogether. 88-36=52!

A G quintuluple sharp would be raised four half steps, or two whole steps, making it a B.
F would be C quintuple sharp.

There is no B sharp.
Ab
B sharp on the piano is C because C is one half step after B :-)
Yes. In music an augmented second is then the second degree is raised by either a sharp or a natural, the interval between A-flat and B natural on a piano is an example.
To the right.
A flat
