No, he does not die, meaning that he is not dead. He's even a character in Kingdom Hearts. Very rarely (except for Aerith) are the Final Fantasy characters that show up in Kingdom Hearts dead in the Final Fantasy games. I think that Aerith is the only one who is dead in Final Fantasy, but is alive in Kingdom Hearts.
Leon is a side character that appears in most of the Kingdom Hearts games. His true identity is Squall Leonheart, the main character from Final Fantasy VIII. In the first Kingdom Hearts game Yuffie (another side character, originating from Final Fantasy VII) calls him Squall, but is quickly rebuffed, as Leon tells her he no longer goes by that name. It is not explained why, however.

Cloud and Sephiroth are in Kingdom Hearts because it's director, concept artist, and character designer is Tetsuya Nomura. Tetsuya Nomura is also the character designer for Final Fantasy VII and since both games are made by the same company, they added certain Final Fantasy characters into Kingdom Hearts. The basic concept of Kingdom Hearts is a Disney/Square Enix hybrid.
