O2 is -2
so Mn is +4
I assume you mean the oxidation number of Mn in the permanganate ion , MnO4- The sum of the oxidation numbers is the charge on a polyatomic ion so Mn has an oxidation number of +7 as each O is assigned -2.
MnO2 manganese(IV) oxide. Oxygen has a -2 oxidation state (oxidation state is a better term here as oxidation number is better used for complexes- they give the same answer for this compound)
The change is from 4 to 3.
The oxidation number of manganese depends on the particular compound in which manganese is present. The most common oxidation states are +2 as in MnCl2, + 4 as in MnO2, and + 7 as in potassium permanganate, KMnO4.
Carbon, Sulfur, CO, FeCl2, MnO2..

-2 for each O, +4 for Mn

MnO Mn2+ and O2- = Mn2O2 but you'd simplify and it becomes MnO
oxidation number of I is -1. oxidation number of F is +1.
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
