Free fall, motion of a body where gravity is the only force acting on it.
Anything falling downward through the air is not in free fall.
because - it falls downwards because of gravity but there is an upwards force (which may be very small but isn't zero) of air resistance (drag).
So just choose four different objects falling downwards through the air
However in space, an astronaut unattached to any object would experience free fall, because he/she would be pulled downwards towards the Earth by the force of gravity but experience no air resistance there being no air in space.
