http://www.exim.org/exim-pdf-current/doc/spec.pdf Should contain the current documentation. Unfortunately, page 1 says that it’s the documentation for 4.82, and that seems to be true.
IIRC, this has been a problem in the past. However, the differences are probably small. You can find the changes at
https://github.com/Exim/exim/wiki/ChangeLog Indeed, it seems there were only bugfixes in 4.84

This can be done with careful configuration. It’s probably easier to use multiple instances.

Yes, just launch exim with a different configuration file, and specify the various locations in that configuration file, or sometimes from the command line, if that’s easier.
