Heat rises, so placing the air conditioner high allows the unit to cool the hottest air that is at the top of the room.
Because the cool air from the air conditioner is denser than the warm air in the room and sinks. Placed high up the cool air will have time to get further from the air conditioner before it settles to the floor, allowing it to cool more of the room. Placed on the floor the cool air will mostly pool around the air conditioner and very little of the room will be cooled. Some air conditioner are actually placed relatively low in a room, but they have fans and baffles that blow the cold air upwards to the ceiling resulting in the same effect as placing the air conditioner high (maybe even better as the fan blows the cool air not only up to the ceiling but across it, possibly covering a larger volume of the room than cool air falling passively from an air conditioner placed high but without fans).
Cold air will sink and hot air will rise. So ACs are placed up higher.

A window already has a casing around it to protect and allow condenser venting. An air conditioner that is made for a sleeve has no protective shell around it, so if you put a window air conditioner in a sleeve you will not get good air circulation from the fan that cools off the condenser. That will result in high pressure at the compressor, high temperature at the condenser and high temperature at the evaporator. This will result in poor cooling and probable compressor failure which will allow you to go out and buy an air conditioner that is designed for a sleeve.

Portable air conditioners come with a vent hose that can be placed in a nearby window or vented through a hole in the wall like your clothes dryer.
It is a matter of preference. However, you do not want a wall air conditioner to be too close to the floor. Usually they are installed about two inches from the ceiling or so.

Usually the manner in which the unit vents. Window air conditioners are contained in a case that has vent holes on the top and side while wall air conditioners are vented in the rear.
On the hallway wall by the return air duct
Unplug it!
Cold air will sink and hot air will rise. So ACs are placed up higher.
Modern wall air conditioners usually do not need any coolant replaced during the life of the air conditioner.
Yep. You get it in there. you can use a central unit if you can get it in there.
A window air conditioner must be fitted in the window. The back end generates hot air and some drip water. Some can fit in a wall but still the back half is outside.
