HELP! MANY CRITTERS TO ID

[Apheoxx]

I have a few critters to ID and I hope none of them are bad. I have supplied a slew of pictures, with no clear meaning or direction.

1. I have a few clear/gray blob things around my tank that are just popping up and I’m not sure what they are.

2. I have a few root-like structures around the tank that are also just popping up.

3. I have a very weird squiggly line in one of my corners. (May not be a critter?)

4. I have these weird things on the baffle walls of my sump that are very small and oval shaped, translucent if you may.

5. (Not in the pictures) - I have a little white worm with many legs in my sump, he looks like a micro centipede (not a spaghetti worm).

PLEASE help me find an answer to all of these mystery hunts! Thank you so much reefing community.

Looks like a bunch of sponges

1 - sponges (harmless filter feeders).
2 - more sponges (different kind; harmless filter feeders).
3 - the translucent white squiggly lines look like they may be an egg ribbon/case (some mollusks lay ribbons like this), but I can’t say for sure from the pic.
4 - probably the pineapple sponges (harmless filter feeders) in the pics, but if you don’t think that’s right than circling what you’re asking about may help.
5 - need pics to say for sure, but I’d guess from the description either some kind of bristle worm (polychaete) or a sea cucumber of some variety.

Some kind of bristleworm - I'm not sure what kind, but the odds are really good that it's harmless.
