I am guessing you are running LEDs? they create a distortion that makes it really hard to view the true corallite structure, can you take a top down pic? would help see the morphology/ structure of the radiular corallites more clearly.

I hope this helps. I know they aren't the greatest but it was the best quality I could manage

Looks to be Acropora macrostoma or Acropora microclados

I have a quick question regarding polyp extension. My newest acro (not pictured above) acclimated on my sand bed for about 2 weeks then went into its new spot. I've noticed that it has significantly more polyp extension on the "dark" side of the frag, meaning the side where the light doesn't really hit it. Is this a sign I should lower the frag and get it a little less light for the time being? Other than that the coral has shown no other negative effects.

I would leave it where it is positioned, pics of said acro? also lighting? a behavior of LPS corals and octocorals is to expand more to absorb more light, I wouldn't be surprised if some acros dont do the same.
Daytime polyp extension is only a "decent" indicator of coral heath with Acropora, I have observed good day time polyp extension on some acropora that were STNing while working professionally in the hobby. A good sure sign Acropora are happy is if they exhibit nocturnal axial corallite polyp extension regularly.
Growth of course is also an good indicator. The (Nocturnal Axial Corallite Polyp Extension) is a pretty well known belief among old school "acroholics", and I have witnessed it. When I worked for a LFS in college I saw it with my own eyes, The imported wild colonies that we got in, if they exhibited the (NACPE) right before the actinics kick on you knew they were stabilized colonies, ones that chronicallly didn't exhibit NACPE usually bleached, RTN or STN.

Hard to tell at this size and picture quality but Acropora aculeus would be my guess.

I know this thread is almost a year old but I have the same 2 acropora I was originally asking for an ID on. After a year of growth, maybe it's easier to tell the IDs. Let me know what you think.

first acro, mostly encrusted growth unfortunately.

Second acro.
