No idea... starting at bottom of tank... dying?

Got these four from a guy on the street. Any body have any clue what they are? Some look like they are getting white edges...

Tank has been set up for a year or more now. Got other inhabitants all doing well. Params are near perfect.

I think 1, 2, and 4 are LPS corals. You might have a better chance re-posting in that ID forum. 3rd pic kinda looks like a montipora but it's hard to tell from the picture.

Shoot! Ok. I will repost. I think you are right about the montipora. Is the white edge bad?

The picture isn't very clear but that white edge is most likely just the new growth which is good.
