confirm coral types - confused

[Turkey head]

Hello, I have a few branching SPS that seem to be doing well but as they grow some of them don't match what I was told at the LFS and they don't look like the pictures online of that type. Any help IDing would be great. Not looking for specifics, just Stylophora, digitata, birds nest etc. They're about 4 inches apart from each other, will that be a problem as they grow or are they related enough?

This is supposed to be a Montipora digitata I think.
picture from when bought

now with new growth.

This was supposed to be a birdsnest.

now. looks like too much polyp extension for birds nest?

This is supposed to be a Montipora digitata.

looks similar now, just regrowth of the thinning polyps.

This is supposed to be a stylophora. I don't have a before picture but it looks similar, just a little thicker now.

All correct but third looks like birdsnest. Definitely not a digi. Some birdsnest as frags look like that, I have a pink one that I was convinced was a pocci but isn't, it's a stylo aka birdsnest.
