Are you kidding, these are very easy. I write Jazz Chords for fun.
For instance, one of my more simple progressions is:
|:.C∆9. . . | .A-11. . . | .D9sus. . . | .G6. ,^G7. :|etc.
The chords you posted are ametuer chords, unless there is some kind of rythem or /(Note) extension that seems hard, in which it will take you practice. If you want to simply learn basic music theory to find out what to play on a chord, use the Root + 3rd and 5th for starters. Start at the root and go up 2 whole steps, then add annother note either a 4th down or a 5th up depending on what sounds better to you. For a 7th, add a note a whole step down from the root or go an octive up with the root with your 4th finger and move down 2 frets.
