Five balloonist discharges the same amount of hellium to decent back to their camp below 1000 ft. below for breakfast.

One of them left his sandbag while the others still got 1 ,2 ,3 ,4 Lbs of sandbag so that the respective speeds is 1 ,2 , 3, 4, 5. fps

In order to arrive altogether at the same time to the campsite they may use the ropes to pass or exchange their sandbags with the others at any time.Starting all on the edge of 1000 ft plateau, how would they plan the return with minimum passes or exchanges?
