These are all second hand high intensity diffusion pump magnets.  Safety precautions must be observed when dealing with theses magnets.  Safety glasses are recommended.  This is due to the fact that these magnets will fly together with enough force to pinch fingers, chip and break the magnets, and eject tiny pieces of the magnets at high velocities.
