Ages get ret-conned and changed constantly so its hard to keep up.

I'd say the original class of X-Men (Scott, Jean, Bobby, Hank and Warren) are in their late twenties-early thirties. In New X-Men #138, Emma states her age to be 27 which would probably make her 28-30 at the moment.

Magneto is around 80 but physically he's in his prime so around late 20s early 30s as well. Professor X is probably in his 50s by now.

Daken is in his late 60s early 70s, Wolverine is around 140-150. Mystique is over 100 as well, probably 120-130. Sabretooth is around Wolverine's age, possibly slightly older or younger.

The New Mutants, Shadowcat and Jubilee are probably in their early twenties. Hope Summers is 18-19, as is Transonic.

Selene Gallo is somewhere around 20 000 years old (she states her birth to have been "After the oceans swallowed Atlantis and before the rise of the sons of Aryas". Apocalypse is around 5000 years old. Namor is in his 90's.

Quicksilver and the Scarlet Witch are probably mid twenties to early thirties (they are around the same age as the original X-Men and were teenagers when they joined the Avengers).

Captain America and Tony Stark are probably in their thirties. Reed Richards and Doom are probably in their forties. Bruce Banner is probably in his mid thirties. Spiderman would be in his late twenties-early thirties.
