EDIT: Solved. A Basin wrench.
I actually don't know what the part is called, the one that is for hot or cold water on each side of the faucet. It's leaking so I either need to replace it or try to fix it. I tried so hard to undo the pipes or that big nut that hold the lever from the underside. No luck. No wrench fits there. Not sure what to do.

I think you need a basin wrench if I am understanding your question correctly
