How many space shuttles have gone into space and name them?

Six space shuttles have gone into space. The U.S launched Columbia, Challenger, Discovery, Atlantis, and Endeavor.

As of April 5th 2010, 130 launches of the Space Shuttle have been successfully reached orbit. This obviously does not include STS-51L, of the orbiter Challenger but does included STS-131 (Mondays launch of Discovery)

In September, NASA will end the 30 year Space Shuttle program after 3 more launches, STS-132(Atlantis), STS-133(Endeavor), and STS-134 (Discovery). It'll be a sad day for most in NASA.
