3 astronauts flew on multiple Apollo missions
* Jim Lovell - Apollo 8, Apollo 13 (intended to land) * John Young - Apollo 10 (later landed on Apollo 16) * Eugene Cernan - Apollo 10 (later landed on Apollo 17) No astronaut has walked on the moon more than once.
Additionally 3 astronauts would have flew on multiple Apollo missions and possibly walked on the moon more than once had the program continued past Apollo 17
* Dick Gordon - Apollo 12 (had been slated to land on Apollo 18) * Fred Haise - Apollo 13 was scheduled for Apollo 19 * Stuart Roosa - Apollo 14 (he had also been slated to land on the moon with Apollo 20)
The question is not clear, there were three astronauts at a time in a Apollo mission , and there were 11 Apollo missions.
A total of 24 US astronauts have been to the Moon, and 12 have walked on its surface. There were a total of 27 astronauts on 9 Apollo lunar missions, but three of these went twice. (see related question)
Three: Gus Grissom, Ed White, and Roger Chaffee.
Even though Apollo one burned up killing the three astronauts, in all there were a total of 11 Eleven manned Apollo moon missions. They were Apollo 7, 8, 9, 10, 11, 12 , 13, 14, 15, 16, 17.
Between 1968 and 1972, eight Apollo missions took astronauts to the moon,and entered lunar orbit before returning to Earth.Six of those missions dispatched landers to the surface, carrying two astronauts in each.

There have been six Apollo missions that have landed on the moon. But many other unmanned missions.
Eight space missions orbited the moon, carrying 24 astronauts. All were men from the USA who traveled to the moon as part of NASA's Apollo program during the period from 1968 to 1972. Six missions landed on the moon, and their 12 astronauts walked on its surface. No man walked on the moon more than once. And nobody except the 24 astronauts on the eight Apollo missions has ever been farther into space than "low earth orbit".

3 astronauts on Apollo 13 one of them did not go up but he went up on Apollo 14.
17 Apollo missions altogether.
