A good lesson but a couple of corrections: sus2 and sus4 chords don't have a third. D5 doesn't mean the 5th is in the bass. It means the chord has a root and fifth but no third.

Half-diminished is not a diminished triad with a major 7th, it's a diminished triad plus a minor ("regular") 7th. Full-diminished has a diminished 7th (which is the same as major 6th).

IMO the easiest way to play a C9 chord is x 3 2 3 3 x. It's a good shape for all 9th chords.
