Ramanuj,
The clue seems to be the lines that include "host name not found:". It looks like your DNS server cannot resolve the host name to IP address for the list of ntp servers listed in your ntp.conf file. If your server does not have access to those ntp servers, you need to change your ntp.conf file to include ntp servers that can be accessed. If you should be able to access those servers, you may need to look into DNS or networking to find out why it can't see those servers.
