One way for refrigerant to escape the system is through a leak. This will be identifiable by an oily residue at the source of the leak commonly around joints and bends in the lines.
No. You may be leaking engine coolant from the heater core or leaking refrigerant oil from the AC evaporator.
It could mean that there is a leak in the system near the spot. The system cycles oil with the refrigerant, and when the refrigerant escapes through a leak it can release oil, which will leave an oil spot.
A little oil will escape with the refrigerant. Look for a blackish oily stain on the tubing. A service tech might use electronic sniffing equipment.
The correct spelling is "o-i-l-y".
your hand is oily.
A scalp that is oily
Refrigerant compaticilty is about suiting the refrigerant to your refrigerant system. Every cooling system has refrigerant in it which depends on the type of system you use. If the refrigerant not matches with your system, it wont work. This is refrigerant compatibility.

Does it have an oily feel to it? If so, then it's probably the lubricating oil for the compressor. If the oil is able to escape the system, then the refrigerant most certainly is, as well, and you're going to end up bleeding it all out.
Disposable refrigerant containers are only used for virgin refrigerant.
Depending on how oily it is, it can look wet.
