Yes, window air conditioning units require refrigerant, such as Freon, to properly cool the air.
Window AC units CANNOT be recharged at any reasonable expense. They normally hold about 8-14 onces.
No easy way of doing this. These units do not come with service valves.
You can add a tapping valve(which almost always leak after a long time) or braze in a schrader valve.
Depends on the air conditioner. Older units use a form of Freon that is no longer manufactured, and you cannot buy it. Some window type units are sealed, and have no provision to add refrigerant. Your best bet will be to talk with the service staff at a local heating and air conditioning company.

yes
no. it is not a good idea. new hfc refrigerants require a different type of oil than the R22 units. the new refrigerants typically run at higher pressures than the R22 units.
If there are no leaks, it would not need recharged.If there are no leaks, it would not need recharged.
Some portable air conditioning options that do not require window exhaust include evaporative coolers, portable air conditioners with a self-evaporative system, and personal air coolers. These units can be used in rooms without windows or where window exhaust is not possible.
Yes, it's very wasy to install a window AC unit. Most single room AC units just need to be placed in the window opening and the cover flaps secured to the sides of the window sill with a couple screws and that's it. AC units are designed with a weight distribution which will support it's self in the window. There are bigger ones which require a support but those are easy to install as well. Instructions come with all new units.
actually this is a pet project of mine to produce a Freon-less A/C unit
