There are technically four, but only three are spaceworthy:
OV-103 aka Discovery
OV-104 aka Atlantis
OV-105 aka Endeavour
OV-101 aka Enterprise exists but is a non-flying shuttle. It was built as a demonstrator but was never built to fly in space although in theory it could have been dismantled and made spaceworthy -- a very expensive proposition.
Currently NASA have three space shuttles Discovery, Atlantis and Endeavour.
NASA built a total of five space shuttles: Columbia, Challenger, Discovery, Atlantis, and Endeavour. These shuttles were in operation from 1981 to 2011.
As of September 2021, NASA does not have any shuttles left to launch. The Space Shuttle program was retired in 2011, with the final mission of the Space Shuttle Atlantis. NASA now relies on commercial partners and other space agencies for crewed missions to space.
Two space shuttles have crashed: Challenger in 1986 and Columbia in 2003. Both incidents resulted in the loss of the crew on board.
