I need help Balancing these using the Redox Way...?

Question

I need each step that you did for doing these. For Example:
SbCl5 + 2KI >>> SbCl3 + 2KCL + I2
the steps:
Sb + 2e- >> Sb
+ 2I - 2e- >> I2
----------------------
Sb + 2I >>>> Sb + I2 (^^Is that Right?^^)
If you dont want to do each step, its fine. But i chhose the best answer based on WHATS BEST!!
Here is the Probs:
1) Mn O2 + H2 SO4 + H2 C2O4
2) SbCl5 + 2KI >>>> SbCl3 + 2KCl + I2 << done, but is it right?
3) S + HNO3 >>>> SO2 + NO +H2O
4) HNO2 + HI >>>> NO + I2 + H2O
