Yep another what did I buy thread

So I know it is really hard to tell what an Acropora is just from a frag, but I am hoping for some help so I can determine mainly height in my tank. Just want to place them height wise relative to each other.
Any help with Identification would be much appreciated.

I'm not sure what they are, if they are a named variety of Acro, but they all look like they're in good shape! :)
