Airbus 380 take-off weight ism 1,200,000 pounds.
to take off the the aircraft which is operated at a specific speed on the runway
This varies depends on the size of the plane. A smaller aircraft like Cessna would need a very less take-off speed than a Boeing. The average take-off speed is 280kmph.

Depends on WHICH Aircraft you're talking about.
what type of aircraft are you talking about? it varies for every type.
Depends on the aircraft, can be anywhere from 40 to 160 mph.
If conditions (airport layout and traffic conditions) allow aircraft take off and land against the wind (headwind). This way the aircraft can take off or approach the runway at a lower ground speed.
No. The speed of takeoff depends on multiple factors including (But not limited to): aircraft weight, wingspan, wind speed, and aerodynamics of the aircraft. For example: A Hang Glider takes off at a significantly slower speed than a 747.
Differs in every aircraft but mostly around 160kias.
Take off speed is different for different aircrafts. There is no one speed for all aircraft. Usually depending on the load etc, take off speed would be the speed at which enough lift is generated to enable the aicraft to lift off the ground.
Light propeller driven aircraft can take off as low as 50 mph. Basically the heavier an aircraft is, the higher speed it takes off. - A fully laden 747 will take off at approximately 170 mph.
