Small planes (piper, cessna etc.) about 70-110 mph. Medium planes (727,737) about 190- 230 mph. Large planes (747,757) about 230-265 mph.
No.
This is a very broad question considering how many planes there are. Most single engine propeller planes take off around 70 mph. Commercial airliners around 140 mph. It depends on the aircraft.
That varies from about 50 mph for a Piper cub to about 150 for an airliner to over 200 for some military jets.
Yes.
