Anything that takes placce in the Marvel Omniverse is canon,
certain crossovers that comply with Marvel's established continuity are Canon.
616 is the Prime Reality/Universe of the main Multiverse within the Marvel Omniverse,
every Alternate and Diverged Reality derives from the 616 Universe,
in other words, every Other Universe in the main Multiverse is but a copy of the 616 Reality,
In the case of the Alternate Realities, they are the same as 616 but with different histories, for example, the Hulk may be able to fly, or the Hulk may be a speedster instead of a uber strong brute, but it's still Bruc Banner.
In the case of the Divergent Realities, they are exactly the same as 616, same history, same everything, but they are created when a moment in the History of the 616 Universe changes, which Alters the Future thus creating a separate Universe that begins from that moment and then takes on a life of it's own.
This is usually portaryed in What Ifs, but there are other titles like Adventures of the X-Men.
