The car that rolled is not responsible, the hit and run driver is responsible. However if the police do not find that person, you are out of luck unless you have comprehensive insurance (full coverage). You can try to talk to/sue the parking lot owner...Talk to stores that may have video coverage of the incident...
The driver that hit the parked vehicle would be at fault.
The owner of the car that was wrongly parked still has the ability to sue. They should get the other driver's information and file a claim on their lawsuit.
driver of parked vehicle
Generally speaking, the driver in motion is considered to be at fault when a parked car is hit, even if the car was parked illegally. The exception to this would be if the car was parked in a dangerous, hard-to-see location and the driver in motion could not have reasonably avoided hitting it. For example, if a car is parked on a sharp curve in the travel lane of a narrow road, and the driver of a car driving around the curve at the speed limit would not be able to see the parked car until too close to it to avoid a collision, then the driver might not be liable for damage to the parked car, and indeed the driver who parked the car might be liable for damage to the car that hit it.
If the other vehicle was parked, there was no other driver to have license, insurance or registration. The driver who hit the parked vehicle is at fault and is liable for all damages to the parked vehicle.
If the car was legally parked, Yes.
Anytime a car is entering traffic from a parked position, it is that driver's responsibility to make sure that the lane is clear before moving into traffic. The driver of the car entering traffic would be at fault.
I believe you are "standing", not parked.

To avoid the car from rolling forward.
The handbrake is used to stop a stationary car rolling downhill. The transmission can also stop a car from moving when parked.
The driver of the car that was driving when the accident occured. The owner of the parked car should not be responsible unless the car was parked in an illegal place or position.
