In FeO the oxidation number of iron is 2+ and the oxidation number of oxygen is 2-.
The oxidation number of Fe in FeO (iron oxide) is +2. Oxygen is typically assigned an oxidation number of -2, so since FeO is a neutral compound, the oxidation number of Fe must be +2 to balance out the charge of the oxygen.

The oxidation number of iron can vary, but it is commonly found at +2 or +3. In some compounds, like Fe2O3, iron is in the +3 oxidation state, while in others, like FeO, it is in the +2 oxidation state.
The oxidation numbers of iron (Fe) can vary depending on the compound it is part of. For example, in FeCl3, iron has an oxidation number of +3, while in FeCl2, its oxidation number is +2. In elemental form, such as in Fe metal, the oxidation number is 0.
The oxidation number of iron in Fe3O4 is +2. This is because oxygen is assigned an oxidation number of -2 and the overall charge of the compound is neutral. So, iron must have an oxidation number of +2 to balance out the charges.

The compound FeO is actually named iron(II) oxide. This is because the iron in FeO is in the +2 oxidation state, so it is referred to as iron(II) to indicate the charge of the ion. The Roman numeral is used to specify the oxidation state of the metal ion in the compound.
I am going to assume you meant ferrous oxide. Ferrous oxide is also known as Iron(II) oxide and has the formula unit FeO. The oxidation number of iron in iron(II) oxide is +2.
The oxidation number of iron in ferrousofericoxide (Fe3O4) is a combination of Fe(II) and Fe(III) ions. The Fe(II) ions have an oxidation number of +2, while the Fe(III) ions have an oxidation number of +3. Each formula unit of Fe3O4 contains two Fe(III) ions and one Fe(II) ion, resulting in an average oxidation number of +2.67 for iron in this compound.
This may best be demonstrated by example: Here are two forms (read: oxidation numbers) of iron, as FeO and Fe2O3. Because we know oxygen has a -2 charge per atom, the oxidation number of Fe in FeO is II. As for Fe2O3, we know that the oxidation number of Fe is III; there is no charge on the compound, so the two iron molecules must equally offset the -6 charge from the three oxygen atoms. Oxidation numbers are written as roman numerals. You would write these two forms of iron oxide as iron(II) oxide and iron(III) oxide, respectively. Oxidation states are the (+) or (-) charges written as a superscript.
Iron II is also known as ferrous ions (Fe2+). Ferrous ions, has an oxidation number of +2. The oxidation numbers for the "odd" transition metals that have more than one oxidation number are always the number that is written after the element name (Added:) and it thereby is the charge of it ion. So Fe(III), ferric ion, is Fe3+
-2 for oxygen. The oxidation number of iron depends on the oxide. +2 for Fe in FeO. +3 for Fe in Fe2O3. +2 and +3 for Fe in Fe3O4. (Note: Fe3O4 can be considered as a mixture of FeO and Fe2O3)
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
