To see how you create drop 2 chords please read Drop 2 chords for guitar which goes over the basic principles. This post contains fretboard diagrams for maj7, min7, dom7 and min7b5 drop 2 chords on the second string set (strings 2 to 5).
All the examples have an Bb root note because that sits on the 1st fret of the 5th string. The shapes go in order starting with the root note in the bass, then the 3rd, the 5th and finally the seventh.
Tip: If you know the shapes for drop 2 voicings on strings 1 to 4 then these are the same shapes but notes on the 3rd string shift down fret.
