Can any individual like me take short position?
Sure, if you can find a broker that will trade futures, you can take either a short or long position. You will most likely have to use a margin account and mark-to-market (adding funds if you're losing money) whether you go short or long.
Note that "shorting" futures is actually simpler than shorting, say, stocks or bonds, since you don't have to "borrow and sell" the underlying asset to go short. You just take the short side of a futures contract with another party.
