The helicopter begins to fall because gravity is pulling its weight. As the helicopter accelerates, the air passing past the helicopter creates drag, as the helicopter continues to accelerate the drag Increases until the drag becomes equal to the weight, stopping it from accelerating.

Even if the helicopter did not auto rotate it would still reach a terminal speed, however the terminal speed for the non auto rotating helicopter would be a lot higher and the helicopter would take longer to reach this speed.

Why a helicopter during autorotation could reach terminal speed with out the pilot changing the controls?

Three forces work here. There is gravity, air resistance and the lift force made by the blades autorotation. When the air resistance and gravity forces are equal in strength, this means that the helicopter has reached its terminal velocity. It cannot fall any faster than it is. As the helicopter is using auto-rotation, the pilot does not need to change any controls because the forces will balance out themselves. The helicopter, with the aid of the still spinning blades of the helicopter, will be able to make a safe landing.

What is the terminal velocity of a helicopter?

Terminal velocity is generally associated with a falling object, not a powered one. Therefore I must assume that the helicopter has experienced Engine/rotor failure. Rotor failure is important because even unpowered, the rotor can be used (auto-gyro) to safely land.Let's supposed the rotors have been blown off. The falling body of the helicopter will reach a 'Terminal Velocity' of between 100 and 140 mph, depending on its Drag value. Its drag value will depend on its shape and size.

increase- your speed will increase until terminal velocity is reached. From there it will stay constant.

Terminal velocity if it has reached its top speed. Or obviously constant speed.

What is meant by terminal velocity of a falling object?

The terminal velocity of a falling object is the constant speed where the force of gravity is equal to the force of drag. Then the forces cancel each other out. Essentially, terminal velocity is when the speed of a falling object is no longer changing. It isn't accelerating or slowing. It's constant.
