Hello everyone! I received these super cute succulents from a friend back in May, but have been struggling ever since to identify them! Help a girl out?

Thank you!

Brittany

edit: they are sempervivums (also known as houseleeks), but unknown still on the type.

Hello everyone! I hope this message finds you well!!
Can you help me identify these cacti? (there are three total, I just included multiple angles). I got them from an Amish greenhouse near me, but there were no ID tags. Thank you in advance!
