"Che" is a form of colloquial slang native to Argentina used in a vocative sense as "friend", and thus loosely corresponds to expressions such as "mate", "pal", "man", "bro", or "dude"; as used by various English speakers. The term became a staple when Ernesto "Che" Guevara (an Argentinian) rose to prominence during and after the Cuban Revolution, as the Cuban guerrillas bestowed the term upon him as a nickname to mark his heritage and to recognize him as a friend of both the revolution and the people.
If you mean the nickname of the Cuban revolutionary Guevara, we English speakers pronounce it CHAY. In Guevara's native Spanish it would sound similar, but without the glide towards "ee" at the end; more like CHEH. On the other hand, if you mean the Italian interrogative for "what," it sounds like KEH.
