So the first to pics look like some kind of sponge, the 3rd pic looks like a snail without a shell and the 4th is a clam of some sort maby a cleaner clam? also found what looks to be a baby coco worm/ feather duster but to small to photo and another looks like a baby one of those bad anemones but again to small to capture ill try to get those two later. Thx for any help you can give.

None are the sponge commonly called Q-tip, but all are sponges. Harmless stuff. The last is a little bivalve. Not what is commonly called a cleaner clam because cleaner clams are burrowing clams and would be found under the sand.
