Answer:
I am the state when a person is holding a person inside
I am the building with the most number of stories.
I am owned by every man, though my length differs. Their wives use me after getting married. What am I?
I cut through evil like a double edged sword and chaos flees at my approach. Balance I single-handedly upraise through battles fought with heart and mind instead of with my gaze.
I can fall off a building and live but in water I will die.
What is the middle of water but is not an island?
