It depends on the blades configuration. The blades work just like an airfoil on the airplane. Basically you want the thicker side to face the incoming wind first. Conventionally, i believe manufactures make it to turn clockwise to produce lift.

Most single rotor helicopter systems turn counter clockwise when looking down on the aircraft. Depending on the make and model this may vary. There is no specific reason in particular for this other than keeping with pilot familiarity. When flying you must have your foot constantly on the right rudder pedal to counteract the main rotor blade, many pilots get into a habit of keeping their foot on the pedal (as well they should) so the manufacturers try to stay congruent with the pilots habits. The one thing they dont want is to have pilots not want to fly them because its not comfortable or even worse lose control.

If you look helicopters from above, all American single rotor helicopters have blades turning counterclockwise, but also Agusta helicopters like A109 (USCG MH-68 "Enforcer"), EH-101( the future "Marine One") and A139 have counterclockwise rotors.
This because Agusta started building American helicopters on license and then they kept using counterclockwise rotors.
But not all helicopters are counterclockwise.
Eurocopter (like USCG HH-65 "Dolphin") have all clockwise rotors and also Russian helicopters like Mil(Mi-28 "Havoc", Mi-24 "Hind", Mi-6 "Hook", Mi-8 "Hip") have clockwise rotors, while Kamov helicopters have all contra-rotating rotors.
So we can say that European (except Italian Agusta and British Westland,that is now controlled by Agusta) and Russian helicopters have clockwise rotors.
American and AgustaWestland helicopters are counterclockwise.

There is no advantage of one over the other.
The whole system is designed so that the blades achieve optimum position in the rotational cycle no matter which direction
the blades turn.
As I remember, the blades often turn clockwise, when viewed from above, but there is no scientific reason that this must be the case.

Both. Some models use contra rotating rotors which turn in opposite directions. Most single rotor helicopters turn anti clockwise and the tail rotor is on the right side of the tail boom to counteract the centrifugal force.

depending on the model. CH-47 Chinook turnes opposite directions for it has two blades on top...

it spins as you're doing the tail rotor isn't stabilizing it and it falls Cu's you do not have the carry from the main significant rotor that's that your gyro has failed the reason it falls is that that's spinning canceling the carry
