G# and Ab do not have a semitone between them. So they can not be a major second.

B sharp would be the third of the chord, not the fifth.

A dominant seventh chord (indicated with a 7) does not have a major seventh but a minor seventh. The answer displayed on the piano is therefor correct.

Gb diminished 7th (Gb o7) has a Fbb note in it. Eb may sound the same as Fbb but is not a diminished seventh from Gb.

The B chord obviously does have a perfect fifth.

That should be correct, I will look into it!

The note F is not in A#m, E# is.

A minor seventh chord has a perfect fifth, not diminished.

It is a minor third because the two notes have only 3 semitones between them. A major third needs 4.
