Thanx in advance
my question is having same name servers will hurt my rankings
If you exchange links between all your sites, then many would say this is an unnatural link pattern, and these links may well be 'discounted' by the some search engines.
IMHO having the same name servers isn't that big a deal (think of really big ISPs who have hundreds of thousands of domains on the same nameservers) - it's the interlinking itself that the big deal.
In any case, one-way links to your sites from "the outside" (for some definition of "outside") are likely to be worth more than link exchange.
