YES !! the top of the plane is relatively moving faster than the ground.
Wrong, the top of the plane is not moving with respect to the ground. It it was the plane would move from its position on the runway.
air speed is the measurement of the aircraft speed.
ground speed represents the actual displacement of the aircraft at ground level.
air speed is always greater than ground speed.
Not necessarily. If there is a tail wind the air speed may be less than the ground speed.
consider a record on a turntable , the outer edge of the record
will have a greater angular velocity than the center of the record.
This is probably just a minor error. Angular momentum is measured in degrees per second, or whatever units you using. The linear velocity of the inside and outside of the record will be different, but not the angular velocity.
