Maybe sponge.

Last pic looks like a little clam

*Should* I kill them?

If you feel it will be fun - go for it LOL
SOME FIND THEM neat while others find them annoying to nearby coral
I personally eliminate them

I never did get the hang of the metric system. What is a "metric fk-ton" in Imperial measurements? Is it four boatloads?

I forgot that I'd added any nerite snails -- I don't think I've seen them since.

They're most active at night I think. Mine pepper my tank constantly.

1-3 -- Is each circle an egg, or are there many per circle? Because there is a metric fk-ton of them.
4 -- It isn't anywhere else in the tank. I can't imagine the snails decided collectively to duke only above my nem. LOL

I'm not sure about the Nerites being single or multiple eggs but they plant separate egg sacks, like everywhere & the Cirth snails lay in clusters. Maybe the nem was flirting with a snail. Or the snail mistook the anemone's attention. LOL
