Hey there! Group 4A elements don't really exist as ions, therefore will not have an ionic charge, they will however have an oxidation number, which will vary according to what other elements those are bonded with.

C and Si have -4 or +4 depending on the compound. If you have CO2, then two O bring -4 charge and C brings +4 charge.

Also Sb and Pb have +2/+4 charges. For example, PbO have +2 charge on Pb and -2 on O. On the other hand, PbO2 have +4 charge on Pb and -4 on two O atoms (-2 each).
