per unit, you follow the fight sequence 1 to 6 (where 6 is the consolidate) per eligible unit. You end the Fight fase if you can't complete the number 1 step anymore.
What this man said right here.
Still, you (the unit charging) can only fight what you declare a charge against in the fight phase, regardless of how many times you get to fight in the fight phase (Bezerkers can fight three times with a stratagem). Yes, you might be able to consolidate three times to get into contact with a unit that was outside your charge range in the beginning of the round, but you won't be able to high-five them with a chainaxe to the face. They, of course, now that they would be within 1" of the Bezerkers, could swing at you.
Still, it's a good way to tie up that Leman Russ after you've "Death to the False Emperor"'d all the Guardsmen that were bubble-wrappin' that command tank.
