It depends on what they are doing.
If they are just threatening and demanding the pilots do <x> then let them be. Unless <x> is impossible (I'm thinking of that hijacking in Africa where they demanded to fly to a location beyond the range of the fuel on board) the pilots will do <x> and you'll be on the ground somewhere, almost certainly safer than settling it in the air.
On the other hand, if they are trying to gain access to the cockpit it's no holds barred. Organize as many passengers as you can to take them down, if they have weapons less than guns grab luggage as a shield.
