Which of the following species,$O_2^-$ or $O_2^{2-}$,has a higher bond order?

Among the following species $N_{2}$,$N_{2}^{+}$,$N_{2}^{-}$,$N_{2}^{2-}$,$O_{2}$,$O_{2}^{+}$,$O_{2}^{-}$,$O_{2}^{2-}$,the number of species showing diamagnetism is:

Bond order normally gives an idea of the stability of a molecular species. All the molecules,namely $H_2$,$Li_2$,and $B_2$,have the same bond order,yet they are not equally stable. Their stability order is:

Bond order of $He_{2}$, $He_{2}^{+}$ and $He_{2}^{2+}$ are respectively:
