Sure, ductwork only carries hot air from the source to the living space. It does not matter what the source is.
That depends pn what you mean by `not installed properly`. If it is undersized you may continually kill blower motors and/or heat exchangers, have noise issues and of course not heat or cool the home properly.
It depends. If your bedroom has a supply AND return duct, then no. If there is only a supply duct, and you shut your bedroom door, this pressurizes the bedroom and limits the CFM delivered into the bedroom. A room to room vent or duct would equalize this pressure and allow maximum CFM to be delivered from the central air/heat system.
The air is returning at a lower velocity, so you need a larger size duct.
1" Duct Board has an R-Value of 4.3
With duct tape I install and maintain duct work for a living if you want to seal the joints just wrap the tape around the duct. If you need to cover a hole you will need to screw a piece of metal on the duct over the hole and tape over the edges of your patch. this is the simplest and cheapest way I know to do it.
Only if the existing duct was taking airflow from say, the kitchen, and blowing out of the building.
An air duct is a duct through which air is forced or extracted, which forms a part of a building's ventilation system.

If both systems are forced air systems it's possible to use the existing duct work; however, with out viewing you project, I would suggest having an air duct specialist evaluate your system to determine if modifications are necessary .
Coal miners that are exposed to coal dust are prone to get what is called black lung disease. The coal duct accumulates in the lungs and makes it difficult to breathe.
My parents did it with existing ductwork.
If your apartment does not have duct work, the owner of the building has not had it installed. Perhaps they felt it would be too costly to install, or perhaps they are simply not interested in or see a need for duct work.

Adding central air conditioning to an existing forced-air heating system in a 2,000-square-foot house averages $3,500 -$4,000, and can be done by two technicians in 2-3 days, with little or no change to the existing ducting. If ducts must be added, the work time doubles, as does the cost to $7,000 -$8,000 or more. Estimates for an older, smaller house of 800-1,000 square feet with no existing duct work run $2,100 -$6,000, or as high as $10,000 or more, depending on the type and quality of equipment installed, the amount of space available for installing ducts and vents, and the local economy.
Heat cannot escape the duct as easily as in open air. This results in the same amount of current causing the cable to heat to a higher temperature.
