The lookout post was atop the mast just as a birds nest might be at the top of a tall tree. From that vantage point the bird could see any potential threats that were approaching. The same is true with the lookout in the crows nest. They could see any other ships or reefs or anything that could cause a problem well before anyone on deck might see it.

Crows build nests in the highest point of the tree! This probably accounts for the name, "CROW'S NEST", the highest point on ships.
A crow's nest was used to spot other ships, to spot trouble, to spot land. Since it is high and above the deck a sailor could see for miles around.
A mast or also known as a big pole sticking out of the ships floor.
It depends on the size of the vessel. A large vessel would have a position high in the rigging called the crows nest.
You call him/her just that: the lookout.
