The problem should be clear from the above ntpq -p banner!!  None of the 
servers you have configured have responded to requests sent by your system!

Can you ping these servers and get a response?  Do you have a firewall 
that is blocking Port 123?

BTW, if you didn't wait at least 30 minutes between starting ntpd and 
getting the ntpq banner, you wasted your time!  Ntpd generally requires 
about that much time to figure out exactly what time it is and to beat 
your clock into submission.
