Hard to say, the coral looks to be in rough condition. My first guess would be Turbinaria such as a Pagoda, might be Galaxea, lastly maybe a type of Montastraea. Mountain coral is probably a catch all name.
Jus wanted to give a progress about d coral... I'm happy to say d coral is perfectly healthy n I believe it to be a turbinaria Pagoda as u guys suggested! Thank u so much for ur help!
