Whales are mammals who breathe air into their lungs. Blowholes are a whale's nostrils and are located on the top or back of the whale's head. Blowholes are covered by muscular flaps that keep water from entering them when the whale is under water. In the relaxed state, the flap covers the blowhole. A blowhole leads to the whale's trachea and then to its lungs. Unlike us, whales cannot breathe through their mouth; they only breathe through their blowholes.
There are currently 88 known species of whales, dolphins, and porpoises that have blowholes, so there are potentially 88 blowholes in the world.
Only one. The same as every whale or dolphin.
