It's not weight that allows a person to sink in water, it's lean body mass. The more fat you have the more you float, the less fat the less you tend to float.
If the pulley is fixed (hanging from the ceiling), and the rope passes over it, then 100 lbs of force is required. If the rope is fixed to the ceiling and passes under the pulley (which is fixed to the load), then 50 lbs of force is required.
Correct formulation: "How much does a stone weigh in salt water?"Answer: The same as it does in the air, water, anywhere.
About 21k lbs.
The buoyant force on any object in water is equal to the weight of the displaced water, regardless of how much of the object is submerged.
About 8.35 pounds or 3.8kg
It depends on the density of the object that weighs one pound, and how much of it is under water. The object will weight 1lb - water density * object volume under water; If the object is on average is less dense the water (i.e. is buoyant), and is allowed to swim, its weight will be 0 because proportion of its volume under water will compensate gravity exactly.

It is hard to kick someone out of water. There are many factors into knowing how much force you need. The depth of the water and the weight and stature of the person being kicked is needed to be known.
there is too much water pressure so it will be crushed under all the weight.
Yes and no, it depends how much under weight, if it's just a pound or something you can just gain that, if it's really under weight I would very much worry. It's not good to be underweight or over weight.
It's not so much "needed" as it is a physical consequence. The empty weight is the weight of the aircraft itself - without fuel, crew, passengers, cargo or weapons.
