It's highly unlikely. Falling from such a height would subject a body to a great deal of force upon impact. Bones could be broken, internal organs damaged, and the person would probably be in a state of shock or unconsciousness, so rolling would not be a normal physical response.
No. Falling three stories is a significant height and would likely cause serious injury or even death, making it impossible to roll.
Most probably not. Three stories is a considerable height. When a person falls from that height, the impact on the ground is extremely hard. There are so many potential injuries that could occur, like fractures, head trauma, and spinal cord damage. These types of injuries would prevent any normal movement like rolling. It's not just about the physical ability at that moment, but also the overall state of the body after such a traumatic fall.
