O2is paramagnetic because it contains two 1/2 filled molecular orbitals (pi antibonding orbitals).  Taking 1 electron away O2+ would still leave one 1/2 filled orbital, while adding 1 electron would also leave one 1/2 filled orbital.  Thus those two species should also be paramagnetic.  Adding two extra electrons as in O2^2- would cause the two 1/2 filled orbitals to both become filled leaving no 1/2 filled orbitals, thus making it diamagnetic.
