This shape is played at the 2nd fret, because of the little 2.
This shape is played at the 7th fret, because of the little 7 you can see at the top left.
This one is played at the 9th fret. On this one, you don't play the E or A strings, your two lowest sounding strings, because they are maked with an X, meaning they are not used in the chord.
These are different forms of the B minor chord.
Scale intervals: 1 - b3 - 5
Notes in the chord: B - D - F#
The entire chord is made up of the 1st of the B scale, the 3rd of the B scale (flatted, meaning one fret down), and the 5th of the scale.
Does that help?
