A typical aircraft propellor cuts through the air much like a screw and provides thrust to the aircraft. Many of the modern airplanes have propellors which are variable pitch and they change pitch so that it can increase the blade angle to grab more air or decrease the angle to grab less. When the pitch is changed by the pilot, both (or all 3 or 4) blades change pitch at the same time and the same angle. === === The main rotor blades of a helicopter provides lift and thrust for forward motion. To do this, the rotor controls input a pitch control to the Blade that is moving to the Aft and decreases pitch to the blade moving forward or vice versa. Therefore, unlike the typical airplane propellor, the helicopter blades do not have the same pitch ange. One result of this is that the loads on the blade attachments (or grips) and the Mast have higher bending loads and torque loads and the loads are not symmetrical as it would be with regular propellor blades.
The rotor is like the engine to the propeller. A propeller is the fan like blades on the top that spin to make the helicopter fly.

They commonly have one rotor and one propeller for stability .
It actually has two names (A) Tail Rotor (B) Antitorque Rotor.
A helicopter's rotors are all powered, and a helicopter is capable of hovering. A gyrocopter is pushed forward by a powered propeller. However, the main rotor atop isn't powered by the motor - it's the wind which makes it spin, and that acts as the gyrocopter's wings.
They change the speed and angle of rotor, and speed of tail propeller.
It is called a rotor, and it more closely resembles a wing than a propeller blade
The rotor and rear propeller are turned by the transmission connected to the engine
It is the main rotor of a helicopter that acts to lift and thrust the craft through the air. A link is provided below.
there are a few twin rotor helicopters. The Chinook is possibly most famous.
NO, the main rotor does the lifting and the small rear propeller is used to stop it spinning around and help with steering it.
