B flat and E flat
D flat major and E flat minor.
The G flat key is the black key left to G and right to F on the keyboard.

To play D flat on the piano, locate the black key immediately to the left of the white key D. This black key is D flat. Press it with your finger to produce the sound.
A flat is the name given to the black key directly left to a white key. e.g The black key to the right of C can either be called D Flat (left of D) or C Sharp (right of C). It's the same key and also sounds the same.

Well you find a B and go to the black key on the left

The correct fingering for playing an F flat note on the piano is to use your thumb (1st finger) on the white key directly to the left of the F key.
Any note which is "flat" is always one half step lower that the specific white note you're talking about, B-flat is one half step lower than B, so that is the black key just to the left of B. Thus A-flat is the black key just to the left of A, G-flat is the black key just to the left of G, E-flat is the black key just to the left of E and D-flat is the black key just to the left of D. For C-flat and F-flat, there are no black keys between B and C & E and F so therefore C-flat would have to be B and F-flat would have to be E. Any note which is "sharp" is always one half step to the right of the specific white note your labelling. Thus F-sharp is the black key directly to the right of F, G-sharp is the black key to the right of G, A-sharp is the black key to the very right of A. C-sharp is the black key to the right of C and D-sharp is the black key to the very right of D. For E-sharp and B-sharp, since there is no black key between the notes I mentioned above, E-sharp would sound the same as F and B-sharp would be the same as C. Most of the time when we're talking about "sharps" and "flats", we're referring to a black key.
