Its difficult to understand your question, I can make an assumption (although your stoichiometry is off).
Are you asking about Iron Oxide compounds?
Iron is a transition metal, abbreviated "Fe." It has two oxidative states, +2 and +3--often written as Fe (II) and Fe (III).
If you have Fe(II) oxide, FeO, it would be called "ferrous oxide."
If you have Fe(III) oxide, Fe2 O3, it would be called "ferric oxide."
The other forms in your question aren't correct and I cannot answer them.
