Comments

C7: The pictured guitar version don't include the fifth (G).
Cm7: The pictured guitar version don't include the fifth (G).
C6: The pictured guitar version don't include the fifth (G).
Cm6: The pictured guitar version have an alternative root (Eb), and could also be named Cm6/Eb.
Cmaj9: The pictured guitar version don't include the fifth (G).

As notable, often the case here is that the fifth are excluded. This is alright since the instrument sometimes force omitted notes and the fifth are the least important note concerning the sound characteristic of the chords.
