Yeah, I see sponges, bubble algae, some other algae, and some spirorbid worms (I’m not seeing any vermetids here, but they may be there somewhere).
Unless they’re invasive and start growing over your corals, the sponges are harmless filter feeders; the spirorbid worms are harmless filter feeders too; it’s generally recommended to remove algae, especially bubble algae as bubble algae tends to be invasive.
