Help confirm LR worms/hitchers?

[cryptrix]

Can anybody help me confirm what I’m looking at in my LR here?

#1 - Larger white tubes (feather husks?)
#2 - Small white spiral tubes everywhere (dead?)
#3 - Small brown spirals, short tubes, translucent ends sometimes?
#4 - What looks like several scales but is probably a curled up worm

Especially wondering if 3 and 4 are vermetid.. Thanks!

Edit: Added a few more pics

The circled things in pic 1 are vermetid snail tubes; the white tubes next to them (one is easily seen in the top right corner of pic 2) are feather duster worm tubes; I'm not sure on pic 3 but based on pic 7 it looks like it may be vermetid tubes next to feather duster tubes (as a genera rule, vermetid tubes have spiral bases and a shiny/nacreous interior while feather duster tubes may curve/turn but wouldn't spiral at the base and are matte inside); pic 4 is more feather duster tubes; pic 5 is a feather duster on the top left and a bunch of Spirorbid worms (mini feather dusters known for their spiral tubes); pic 6 is another vermetid tube.
