mass of the object (times) gravitational acceleration (times) height the object reaches.
When an object is thrown upwards, it loses 9.8 meters per second of speed due to gravity acting against its motion. This is the acceleration due to gravity on Earth, which causes the object to slow down as it moves upward.
A disc is thrown through the air for 1.5 min with a power output of 12.5 W. How much work is done when throwing the disc?
Basically, the upward force has to counteract the downward force of gravity. Thus, the upward force has to be equal to the object's weight. There is not much calculation to do here; just use the standard formula for weight: weight = mass x gravity Under normal Earth gravity, you can use 9.8 for gravity; thus, every kilogram has a weight of about 9.8 newton, and therefore requires an upward force of 9.8 newtons to keep it in balance.
It depends on the magnitude of the force and the mass of the object
The work done on an object is calculated by multiplying the force applied by the distance moved in the direction of the force. In this case, the work done would be 18 joules, which is equal to 6 newtons multiplied by 3 meters.

If there is no vertical motion, then no work is done by any vertical forces.
This is true when the object lands at the same height as it was thrown, but not necessarity if the two are different. You can think of the motion in two parts; it moves upward and it moves sideways. If you throw it at a high angle, it won't have much of the sideways motion and won't travel far. If you throw it at a low angle, you won't have much upward motion and it will hit the ground before travelling too far.

If it was thrown hard enough. Than again, pretty much any solid object can shatter a window if thrown hard enough...

Because they are in Earth's gravity well. They would have to move much faster than you can throw them to keep going up instead of falling back down.
You have only done as much external work on the box as the distance it moves: work = force x distance. If it does not budge no work is done on the object. You have done "internal" work on your muscles which converts to heat energy, but technically speaking, no external work is done on the object
