Coral Identification 2

[Allyt30]

Hi all! I've just acquired some corals and I have absolutely no idea where to start. I was hopping that some of you all here might be able to help me out? The pictures are below with a ruler in the photo as well. I am looking to either identify them or find out how much they're worth. Any help is appreciated.

This is the second of this post because I had more coral photos to upload.

Well, for starters, those all appear to be dead coral skeletons. That makes their value essentially $0. Hope you didn't pay too much for them!

As rocks for your tank, about $3/lb

They were actually just something that was donated to the local nature center I work for. Do you have any ideas about the type of coral they are?

First two look like pocillopora or birds nest. Second looks like acropora, I have seen that last one in LFS but cannot remember the name. As billdogg rightfully points out though, they are the skeletons of formal coral, but very pretty nonetheless.
