Coral ID doubt

[bulabr]

Hello Guys

Please, could you help me with the identification of the corals as the pictures? I bought from one guy that was closing his tank and as I'm beginner in this hobby, I don't know very well about the identification yet.

Those are pretty ambitious to keep when you're new to the hobby, how are your parameters? SPS need stable water conditions, if you drip kalk in your ATO then it should help but it can be a bit of an uphill climb with those when you're first starting out.

The pics are pretty blurry to give good guesses. The best I could see is the second which might be A. formosa growing funky.

And the forth one might be A. nana or A. valida.
