Yes, this is possible.  Unison creates an archive file for each pair of
roots.  As long as all five machines have unique names then you're ok. (If
this assumption is a problem, look at the UNISONLOCALHOSTNAME environment

If you're using unison in a unidirectional manner (ie, -force) from a
central hub to four mirrors then you shouldn't have any trouble at all.
If all five machines are modifying the data simultaneously then you run a
risk of conflicts (obviously).  In that usage scenario you really want a
networked file system rather than unison.

I don't know about the mailing list administration, but unison-users is a
better list for these questions.
