is there any way or website that can allow us to sell our Airmiles??
unless he has flown with them or immediate family membersNearly all loyalty programs have the same term and conditions.
Virtually all prohibit bartering or selling of points and miles.
Some even have special restrictions in place to avoid it, some airlines that will not take award bookings for anyone other than the account holder unless he has flown with them or immediate family members, others limit the number of nominees or restrict certain actions on bookings of anyone else other than the account holder.
If you're found to be breaking TnC they'll suspend you account and you'll forfeit all your miles. It has happened, and it still does happen.
Just use them for hotel stays, dining, car rentals, events and others. But the value of any redemption towards gift cards or other parties is usually very poor to a point that is considered wasteful.

Which have such restrictions more specifically from Magnus point? So far I have used only vistara points and it allows anyone to be added as nominee with 8 nominees per year limit.
That link says about Turkish. But for Turkish, I heard they allow free miles transfer from one account to another account, which is even better. Is that not true?Booking a Turkish Miles & Smiles award for a friend

But as exciting as Turkish Miles & Smiles can be for some of its sweet spots, […]frequentmiler.com
Seems Vistara inherited the nominees system from Singapore Airlines to curb misuse.
Most carriers aren't usually an issue, however do mind selling/bartering is still forbidden.
There's hundreds of pages about this in FlyerTalk of people who have gotten their accounts suspended or miles forfeited.
