1) Armor of God possibly
2) Wish I knew, I've got some of them as well and can't figure them out
3) Cammiothelias
4) Devil's Armor ? Nice Purple Deaths on the left there
Dont know what you paid for pic.#4 but you have some good trade value on those.We have a few frags of those and they are very popular.If you decide to frag them you have a good barining chip there.
