I have my one site listed in google directory and the link information is wrong there. Could anyone tell me how we can contact the editors and change my link information for my website link in google directory....
The Google directory is actually just DMOZ [dmoz.com]. You'll have to go to DMOZ and try to get the changes edited there...then you'll have to wait until Google actually updates their copy of the DMOZ data for it to show up there.
Google now supports the NOODP tag, that's the quickest way to get your description changed in the serps. You may have grandkids by the time you actually hear anything back from DMOZ.
Update submissions (via the "update listing" link on the Open Directory category page in question) are fast-tracked, actually. I have written up a few basic hints here [webmasterworld.com].
