First picture seem to show mushroom corallimorphs and zoanthids on the lower right. Second picture shows a Euphyllia at the center, plerogyra sinuosa (or its skeleton) on the right, Palythoa polyps below it, Orange sea sponge above it and some rhodactis mushrooms all around.
Seems like you've only recently started your marine tank. Please be informed that BEFORE you can put anything living (corals, fish, invertibrates, etc...) in, your tank needs a cycling period of 4-6 weeks.
Search our forum for steps on how to properly start a tank so that you don't waste your money and so that livestock will not suffer/die needlessly. And before you buy any livestock, check that what you intend to put into your tank are fully compatible with each other.
Cheers and good luck. With the properly patience, discipline, and attitude, your tank will give you many moments of satisfaction.
