As long as the fixer hasn't been used, it should be fine indefinitely.
The same goes for stop bath, which is typically just glacial acetic acid. I've used bottles of glacial acetic acid which were at least 50 years old(not for stop bath, but in other chemistry experiments) and they worked fine. Photographic stop bath is a lot less demanding of an application that some of the things I've used it for.

Depends on the use. The chemicals deplete when you use them and just stop working properly. When stored in bottles I believe they hold indefinitely.
Developer holds about a year (those should always have an ex-date)
