How to redeem or exchange coins we get through Airdrop, if they are not listed in any major exchanges???

It'd be quite difficult to find someone who wants to buy them (but you can still try creating a thread) and you might sell them for much less than what they would get you later on.
Since you got those coins for free without doing anything I suggest waiting until they become available on exchanges and at that time you can sell them. And I'm 100% sure you will get more money doing that. So just forget about them for now.
