Having replaced all of the windows recently, you are probably lucky that it
is the side window that opens. Regardless, the amount of work involved is
pretty extensive, and getting a good seal afterwards can be a challenge.

Those two are easy and replacing them will have no effect on the seal.
They are in a metal frame. The back windows would also be similarily
cheap. Copliots side front window would be cheap too unless you've got
one with an openable vent window within it, not many of those around.
The pilots side window, even with the openable window, is not that
expensive.
