Paul, you can borrow up to 8 books, okay.
Literal
Paul, 8-volumes [up-to-まで] [if-なら] borrow-[can-られる] [because-から-ね].
Addressing someone by name, Paul, a non-Japanese name written in katakana. 冊 is the standard counter for bound books. までなら is the conditional scope form 'up to X, if that's the limit.' 借りられる is the potential form of 借りる ('to borrow'). から here is sentence-final giving a reason or background ('since / because'), softened by ね into friendly explanation rather than cold statement. Exemplifies how Japanese library rules or permissions are phrased.
