Number 7-10 never appeared onscreen. That's it and we don't know anything about them.

Number 2-5 are still alive (because they were last seen alive) and their last shot was on the card after Laxus destroyed Wall. Right now they are somewhere on the new landmass, presumably coming back to help Mirajane taking down Jacob.
