To clarify:  A builder can run only one of it’s builds on any specific worker at any one time.  See http://buildbot.readthedocs.io/en/latest/manual/concepts.html#workers

You can certainly run more than one worker on a server.   That would allow the same machine to run more than one build of the same kind in parallel on that machine.
