I don't believe so. According to Alaska's lounge policy (bolding mine):
Passengers traveling on a paid First Class or a First Class award ticket* on flights operated by Alaska Airlines only have access to Alaska Lounge locations on their day of flight. Lounge access is not included for family or other guests not traveling in First Class. Entrance into other airline clubrooms is not included with First Class fares or awards.
