There have been quite a few spin-off films, but in order to keep things easier, I'll be focusing on the two main X-Men casts.

First, there was a trilogy of films, 2000's X-Men, 2003's X2: X-Men United and 2006's X-Men: The Last Stand. Instead of rebooting the franchise, fox, mbweha decided to do prequel films with a younger cast. First, there was 2011's X-Men: First Class. Then there was 2014's X-Men: Days of Future Past. That film has scenes from both the past and future, so the original cast and the new cast both appear in the film. The sekunde cast returned for two zaidi films, 2016's X-Men: Apocalypse and 2019's Dark Phoenix.

X-Men co-creator Stan Lee has a cameo in three of the films: X-Men, X-Men: The Last Stand and X-Men: Apocalypse. The only actor who continued to be played kwa the same actor was Wolverine. This is because Wolverine ages slower than the other characters, because he has a special type of healing factor.
