Welcome to R2R. The first one I'm not to sure about, possibly a hydroid? The last two look like collinista snails and spirorbid worms. @KJ

Welcome aboard, 34clint!

Would agree on the last two - collonista snails (beneficial herbivores, like a mini-trochus) unless you _have_ trochus, in which case they _might_ be babies of those, and spirorbid worms. Those guys are harmless filter-feeders, and as common as can be. Scrape them off if they're blocking your view, otherwise let 'em be.

The first photo looks like young clove polyps of some sort to me. They can be both pretty and invasive.
