You have to pay for filling all the balloons just as you have to pay for feeding all the horses. Using your logic, you could analyze your system at a moment when you are not even filling a balloon and think you have the energy of five balloons pulling for free. It doesn't work that way. When you have balloons number 1,2,3,4,and 5 pulling together, you must have filled all 5 with air. Suppose each balloon can pull 10 pounds up to the surface. 5 balloons can pull one 50 lb object up to the surface, or each individual balloon can pull one ten pound object to the surface. The total weight pulled to the surface is 50 lbs either way.Joe, this has been a nice exchange of views and still I am brain dead, stuck in a rut and common since is not going to set me free.Did the farmer have to feed all four horses, or just one?
Your example was a good one with one small flaw. The process is a linear one but due to the timeline multiple balloons are pulling on the same cable increasing the pulling force on the cable which is greater than the force needed to sustain the system.
I’m going to take my meds, a short nap then later I will return. Maybe by then I will have seen the light, ending this merry-go-round.

That being said, the formula for kinetic energy is 1/2 *mass*velocity squared. The drag of the water will greatly slow the movement of the mass being moved by the buoyant forces. Since the velocity variable is squared in the energy calculation, any reduction of velocity will result in a great reduction of kinetic energy with your device. In other words, the energy absorbed by the drag of the water will be very high.
