1. I think "신나는" is an adjective in this sentence. The sentence means " It was an exciting Friday" and "신나는" is exciting. 2. 저는 금요일마다 밤새 술을 마셔요. => I drink all night every Friday night. "마다" is every in this sentence. 3. 춤을 추다 = "dance", 춤 = a dance, 춤을 추다 = to dance. So, B doesn't make sense, it sounds like " I will a dance" while A means "I will dance" 4. "난 가는 중이야" sounds the most natural to me,
