Hi Kunal,

Yes, you can have multiple email addresses associated with a keypair.
They're called "uid's".  The methods to add a new uid vary with the
GUI you use, but on the command line, you can do:
gpg --edit-key <keyid>

Then at the "Command>" prompt, type adduid.  You'll then be prompted
for the Real Name, email address, comment, as when you first generated
your key.  Don't forget to 'save' your changes.

HTH,
David
