Help with CUC snails ID

[NYC Reef Keeper]

LFS just said they were all ceriths. The brown one that is under the white one looks like a cerith to me, but the other two don’t have spiral shells. Maybe nerites? They all hang out on the glass (mostly at the top) or on the sand, but don’t go on the rock work.

Top 2 can't really tell - not sure it's a cerith though... Possible conch?

Last two pictures are Margarita Snails it looks like.

Second pic is a nerite, those like to climb out. Last one is a margarita

Nerite was my guess as well but I couldn't be positive.
