I want to know how to balance these equations & want to know whether these are 'Redox Reactions' or not.

(1) FeSO4 + KMnO4 + H2SO4 ----> Fe(SO4)3 + H2SO4 + MnSO4 + H20

(2) CoCl2 + Na2O2 + NaOH + H20 ---------> Co(0H)3 + NaCl

(3) [Cu(NH3)4]Cl2 + KCN +H20 ----> NH3 + NH4Cl + 2[Cu(CN)3] + KCNO + KCl

(4) S + NaOH -------> Na2S + Na2SO3 + H20

(5) S + H2SO4 ------> SO2 + H20

(6) FeS2 + O2 ------> Fe2SO3 + SO2

All are redox reactions. You can use either the ion-electron or oxdn. number method to balance them.
