First of all, several pictures that you attached are blur so I couldn't decide anything. Picture number 1, 5, 8 and 9 are coral, Picture number 2 and 3 are sea anemone. and the rest are too blur to be identified.
Number 1 is coral from Genus Tubastrea.
Number 5 seems like coral from Genus Turbinaria because the encrusting life form with rounded tubular corallites. It also have smooth structure between corallites.
Number 8 is coral from Genus Stylophora. It don't have axial corallite so it is not corals from Family Acroporidae. The branches have blunt end and the branches are thicker than Seriatopora.
Number 9 is coral from Genus Goniastrea. It is massive coral, The corallites form meander appearance and thin wall with relatively short valleys.
I agree with Stevanus. Photo 1 is Dendrophyillid Tubastrea; 8 appears to be Acropora? and 9 is Goniastrea. The other Photographs cannot be identified to any level. You may contact me in [email protected] with more photographs.To identify up to species level we need to have a photograph with all details. Dr Quddusi Bashir Kazmi may refer my book on the Hard Corals of India which is available in this ResearchGate in my publications.
