No, just because a human is in water, doesn't mean they will weigh less. Humans would weight the same if they were in pudding, so humans do not weigh less in water.
because there is less gravity in water
Because sea water is more dense than regular water
Because sea water is more dense than regular water
One milligram, if the water is at 4 degrees Centigrade. At any other temperature, the water will weigh a bit less.
Objects under water seem to weigh less but they have the same mass as they would out of water.

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.
because there's less water in it.
no
No. Oil is less dense than water, so 1 liter of oil will weigh less than 1 liter of water.

Less, ovbiously.
