Some macro algae IDs please

[r312h]

I was just curious if any of these things are desirable in the home aquarium, or should I start removing all of them asap. I use ro/di water, and rinse all frozen foods (feed 1/4 cube every other day), nitrates at 5ppm, not sure what else may be causing this algae. I only have about 15 snails in the 55, and running a octopus skimmer at the moment. Thanks for any help on figuring out what these things are.

Sorry pictures are so small, I'll edit them when I get home from work, probably make it easier to see what I'm asking about. Thanks.

1st 2 look like hair algae, can't tell on the 3rd, but possibly valonia, the last is neomeris annulata (Caterpillar Weed) and acetabularia crenulata (Mermaids wineglass).

Caterpillar is on the left, very hard to get rid of. The green is not tasty to any critter that I know of. They thrive in calcareous tanks.

Which picture are you referring to? Thanks

Sorry, just saw ccCapt's response about neomeris. Thanks guys. Should I try plucking everything off the rocks? or is any of that macro desirable?

They tend to thrive when there is excess nutrient in the water. The hair should be taken care of through PWCs and less lighting/feeding.
The other macros will also depend on water nutrient. The neomeris is tough to get rid of.
