D#7 has the following notes; D# Fx A# C#, notice the Fx, the x stands for a double sharp and the musical sign fot that is an x with fatter ends but that is not on my keyboard but yes, double sharps and double flats exist.

Gb6 is made of the notes Gb Bb Db Eb or if you want it with sharps, F# A# C# and D#, so a regular F#.

as to your last question, the chord would be written with the flat 6 between parentheses like this; G (b6).

Hope this clarifies it

Thanks. I wasn't clear I guess. I didn't mean to suggest that the two chords I used as examples had the same notes. I just used the first chord to as an example because I think it seems relatively straightforward as to what the chord is (I would think its a D# with a 7th because a D with a sharp 7th wouldn't make any sense as the sharpened 7th would arguably be the root), but using the same naming convention, the 2nd example seems more ambiguous. But I see that you could use the parentheses as needed in ambiguous situations.
