Looks like an echeveria, (the common name of hen and chicks are actually sempervivums).
Snap them off and replant in fast draining cactus type mix. They root quite easily.
The others are right.your plant wants to spread an make babies.needs bigger pot or be in the ground .morning sun only.and no frost.as it grows thoughs stems that touch the ground will root and.and.pow.make babies.
Anything i say, could be misrepresented, or wrong.
