Fair: without favoritism, cheating, impartial. A fair fight is when two people fighting without any help from anybody. Giving one guy extra boost (say, special gloves) because he is weaker is unfair, but more equal.
I think equality in freedom is fair. Equality in means is comparison and not fair, since you have to be partial and take money from the rich and give to the poor. It would be fair only if the rich actually stole from the poor against the law of the land, but if the rich earned himself (say, he is a successful lawyer) then equalization of means is not fair.
