This was on our chem final today and I'm wondering if I guessed correctly. I thought: Fe(sub)2O(sub)3
right??

Fe valency can be 2, 3 or 5 ?
is there Fe2O5?

This is sort of a trick question.
Iron has two ionized states: it can form Fe(2+) or Fe(3+). Because of this, iron can form multiple different oxides.
Fe2O3 is one of the oxides and is correct.
However, the question is flawed if it didn't give the charge of iron, as Iron(II) oxide (ferrous oxide) or Iron(III) oxide (ferric oxide).
As long as it didn't specify, you are correct.

FeO, Fe2O3, Fe3O4 (The numbers are subscripts)

that is the right answer. however there are other formulae for iron oxide for example magnetite is a form of iron oxide (Fe3O4)

It could be Fe2O3 or FeO.
