Missions- Apollo 1
During a test for what was to be the first manned apollo mission, a fire killed the three astronauts; Gus Grissom, Ed White, and Roger Chaffee. After the fire, the mission was officially chosen to be Apollo 1. 
 

Missions- Apollo 7
Apollo 7 was the only manned Apollo mission that was launched from pad 34 at the Kennedy Space Center with a Saturn 1-B rocket. It was the first manned test of the Command and Service module. The crew orbited the Earth 163 times and it took 10 days and 20 hours.
 

Missions- Apollo 8
Apollo 8 was the first mission to take humans successfully to the moon and back. An important piece to actually landing on the Moon was to test the flight trajectory and operations for getting there and back. Apollo 8 did this successfully and achieved many other firsts including  the the first manned mission launched on the Saturn V,  first manned launch from NASA's Moonport, first pictures taken by humans of the Earth from deep space, and last but not least, the first live TV coverage of the lunar surface.
 

Missions-Apollo 9
The Apollo 9 mission was the first manned flight of all Apollo lunar hardware in Earth orbit and first manned flight of the lunar module. So in other words we had a lot of hardware and computers in space. But Apollo 9 was the first  manned flight of all Apollo missions. Lunar module pilot  Russel L. Schweickart performed a 37 minute EVA. Human reactions to space and weightlessness were tested in 152 orbits.
 

Missions-Apollo 10
The Apollo 10 mission was a complete run-through of the Apollo mission without landing on the Moon. For instance, if you were doing an act, Apollo 10 would be the dress rehearsal before the play. (Apollo 11) The mission was the second to orbit the Moon and the first to travel to the moon. Astronauts Thomas Stafford and Eugene Cernan descended inside the Lunar Module and got within 14 kilometers of the lunar surface. They achieved the closest approach to the Moon before Apollo 11 landed two months later.
