There is a pressure gradient inside your lungs. Plus you have the power to control whether or not water enters your lungs. Many people don't hold their nose when they go under water but because they hold their breath- air can't get out and water can't get in.
Take a straw put your finger over one end of it and then put it in a glass of water, no water will get in the straw.

Lungs are more complex but a similar concept applies.

Because there is air already in the lungs which becomes pressurized to stop the water from entering them.

because you're not inhaling the water when you open your mouth. You're just opening your mouth without breathing in through it.

i would think that is because you are closing your throat or you are blowing out. maybe it is just because you aren't sucking the water in

B/c they're either filled with air or deflated.
