So, you have a benzylic alcohol and two phenols. Are phenols more or less acidic than alcohols? One of the phenols has an electron withdrawing group para to the OH. Do electron withdrawing groups increase or decrease acidity?

More acidic?

the stronger the acid, the easier it will be to remove a proton(H⁺) from it.
