In order for a magnet to repel, the same amount of energy has to be spent pushing into its field. Even if you arrange the magnets in a circle like that, and use the repulsion of one magnet to push it into another magnet, to make it push it into the next, and so on, all the energy is still being cancelled out.
If it takes X energy to push repelling magnets close together, the energy from that repulsion will only equal X at most. There is no gain.
