The first one is bluegill, the second is a pumpkinseed but the last one is new to me. Doesn't looks like an Eastern NA minnow species to me but I'll look at the Peterson guide book right now.
First one bluegil, second pumpkin seed, and the last one is DEFINITELY a longnose sucker. I know the younger ones have a little bit of spots on the back and when spawning they have a long red line along their sides.
