Yes, but there's a strong enough set of conventions in SysVland that it
would be foolish to scramble them around--all you'll do is confuse people.

Alan lists a set of run-level assignments I've never seen before, without
saying what version of UNIX uses them.  It's certainly not SysV...which
confuses the issue since one of the newsgroups in the list is a SysV
group.

If 0 is used for shutdown, 1 is normally single-user, and 2 is multi-user
with no networking; then

as Alan says.

More conventionally, 6 is shutdown and reboot.
