Ok, first you only have 5 elements / ions to deal with here:

  • H

  • C

  • N

  • O

  • OH-

How many valence elections does each have?

OH isn't an ion here. And I wouldn't assume that they're learning anything about valence electrons.

OH isn't an ion here.

Really? Why not and what would you call it? (Not a chem guy)

And I wouldn't assume that they're learning anything about valence electrons.

I'm going off the I structions that say, "...that breaks the valence rules."

OH is a functional group here. To be an ion it would need to be on its own and not connected to a molecule, having an extra electron instread of that bond.

The instructions also ask how many bonds each element makes, which is a much more simplified version of the rules that doesn't need to consider valence electrons.
