If there are multiple combat phases in a turn, a creature that’s been removed from combat can still attack or block in future combat phases that turn.

Removing a blocking creature from combat doesn’t cause the creature it was blocking to become unblocked. If no other creatures are blocking that attacking creature, it won’t assign combat damage (unless it has trample).

Removing an attacking creature from combat doesn’t untap that creature.
