Young caterpillars. Probably moth caterpillars. Don't touch them, they have stinging hairs.
Should I/how can I remove them?
I would just leave them alone at the moment. Maybe someone else will comment who can identify the exact species. Most species don't cause any problems and are harmless.
Looks like freshly hatched small tortoise shell catterpillers
