If you're referring to the theatrical live action films, twice. First time in Superman:the movie, which is his origin story. You actually see krypton for almost half an hour in the film, with Marlon Brando as Jor-el. There's a small flashback in Superman 2, but it's just the same as what you saw in Superman 1. And then it's referenced as a plot point in Superman Returns, as Superman disappears to investigate the remain of Krypton. From what I've heard, they actually filmed scenes of a dead Krypton, and then cut the whole sequence out of the final cut. Some stills are available online if you search hard enough. Hope that answers your question...
No, Krypton has a red sun and his powers only work under a yellow sun. However, this leads to a plot hole because Superman has visited Krypton on many occasions and returned. This should be impossible.
Just one, Grey Lady Down
Superman goes by many names. His first name was Kal-El, which was given to him by his biological parents Jor-El and Lara when he was a baby on Krypton. When he arrived on Earth to be adopted by Johnathon and Martha Kent he was given the name Clark Kent. He was named Clark because that was Martha's maiden name. When he moved to Metropolis and adopted his dual identity, he began fighting crime under the name Superman which, according to Superman: the Movie, was coined by Lois Lane in her first article about him. As Superman he has many other nicknames by which he is known, such as the Man of Steel and the Last Son of Krypton.
