Nasus is just a weak top laner and doesn't counter Fiora. All he can do is slow and then what, kill her with a weak Siphoning Strike because she's denied him so much CS it's not funny. Malphite I can sort of agree on, but he needs to burn a lot of mana to do so. Rammus shouldn't be top laning anyway. Jax is just annoying for anyone.
If you really want to counter Fiora, just remember she doesn't have an effective escape apart from her Q + E combo which she can use to juke onto you for a speed boost. Don't play too aggressively against her and ask for ganks. I would find that someone who can get in nice and easily like Rumble can be really effective.
