Help me identify type of snail?

[Reddd.head]

Hello! I’m new to the forum, but I have question. I took in a few snails from a friend who couldn’t take care of them, but I have no idea what kind of snail they are, I have feeling that they are nerites, but I’m not sure. Here are some pictures. If you could help me identify them I’d be really grateful

Thanks again,

It looks like an olive nerite snail
