The rocket used by the manned missions to the moon was the Saturn V. It consisted of 3 stages: The first stage, the S-IC boosted the rocket to an altitude of about 40 miles before it was separated and the second stage fired. The S-II second stage boosted the rocket the rest of the way to orbital altitude. The S-IVB third stage fired a couple of times - first to achieve low earth parking orbit insertion and then a second time to achieve escape from orbit and send the Command Module and LEM on their way to the moon. The Command Module and LEM didn't really count as a stage - they were grouped with the third stage but the actual booster in that stage was discarded after it gave the boost to send the astronauts on their way to the moon.
