How many team are left for hockey 2013 NHL?

Your very badly phrased question I take to mean, how many teams remain in the hunt for the Stanley Cup.

By the middle of this week, the answer will be four. Conference semifinals will end by Tuesday or Wednesday and the two surviving teams in the west will play each other, while The Boston Bruins will play the Pittsburgh Penguins in the East. The winners OF THOSE series will play for the Stanley Cup.
