If the perpendicular distance from the point of application of the force to the fulcrum is x metres and the perpendicular distance from the crate to the fulcrum is y metres, then the force applied on the crate is 220*x/y N.
We have no way of knowing what power the machine was rated for, but with the information given in the question, we can calculate the power it delivered during the crate-lift: It was (1.96) x (mass of the crate in kilograms) x (distance the crate was lifted in meters) watts.
Potential Energy is given by the fourmulai PE=MGH where M=mass in kilos, G=the force of gravity in Netwons (9.8N) and H=height in meters. So 50*9.8*10=4900joules. A Watt is a unit of power that =1 joule per second. So 4900 joules divided by 5 seconds = 980 Watts, not allowing for losses due to friction etc.
Work = force x distance = Newtons x meters = 1937 Joules.
Force x distance = 100 x 2 = 200 newton-meters = 200 joules.
Provided that the parachute has the same surface area for both of the parachutist's, the 200kg man will hit the ground first due to the extra weight from the heavier man.
F=ma F=200kg*9.80665 m/s² = 1980 N

That really depends on the weight of the crate. Also, on how high you want to lift it. Calculate the energy required to lift the crate with the formula for gravitational potential energy: PE = mgh (mass x gravity x height) Then divide this by the 5 seconds to get the minimum power required. (The actual power is somewhat larger, for various reasons - the initial acceleration required, and losses due to friction.)

Work = force x distance = Newtons x meters = 1937 Joules.
Work = (force) x (distance) = (15) x (5) = 75 joules.The mass of the crate is irrelevant.
The weight of the crate is acting downward on the ground and the ground is exerting a force equal to the weight of the crate upward on the crate.
A collapsible crate is used for transporting things which would be hard to get out of a regular crate. A collapsible crate can be made flat by folding out all of the sides of the crate.
