Identify the metal ions among $\displaystyle \mathrm{Co}^{2+}, \mathrm{Ni}^{2+}, \mathrm{Fe}^{2+}, \mathrm{V}^{3+}$ and $\displaystyle \mathrm{Ti}^{2+}$ having a spin-only magnetic moment value more than $\displaystyle 3.0$ BM. The sum of unpaired electrons present in the high spin octahedral complexes formed by those metal ions is $\displaystyle \_\_\_\_$.
