Yes
R12, or chlorofluorocarbon-12, reacts with ozone in the stratosphere, breaking down the ozone molecules. This leads to a reduction in the ozone layer, which is important for shielding the Earth from harmful UV radiation. As a result, increased levels of R12 can contribute to ozone depletion.
CFC is an abbreviation for the class of chemical compounds known as Chloro-Fluoro-Carbons.
CFC's are dangerous. These CFC's result in mass depletion of ozone layer.
Humans produce CFC's. These CFC's react with ozone to deplete it.
CFC's are ozone depleting substances. HCFC's are an alternative to CFC's.

R-12 is a CFC. It releases chlorine and fluorine.
Freon wasn't banned - Freon is a name trademarked by DuPont for a line of CFC and HFC refrigerants they manufactured. What was banned were CFC refrigerants (such as R12). They were banned from further production due to the negative environmental effects they have.
Chemical instability of mixing a CFC and HFC together increases the risk of fireExcessive system pressure resulting in damage to or destruction of AC system componentsImproper lubrication of the compressor since the R134a won't carry the oil used for R12 systems properly
CFC is Cloroflurocarbon and it refers to the Clourine, Flourine, and Carbon that are present in Freons such as R12. Most home AC units use R22, which is a HCFC, that is HyrdoClouroFlouroCarbon. Any Freon that starts with R requires a EPA license to purchase, and any that ends in A (such as 410A or 134A) is available to the public.
Mixing 404A refrigerant with R12 is not recommended, as they are incompatible and can lead to system damage, decreased efficiency, and safety hazards. R12 is a CFC refrigerant, while 404A is a blend of HFCs that operates at different pressures and thermodynamic properties. Additionally, mixing refrigerants can complicate recovery and recycling processes, making it difficult to maintain compliance with environmental regulations. It's best to use the specified refrigerant for your system.
Depends on which type of refrigerator. Some industrial units still use pure ammonia. The CFC refrigerators typically used R12, just like car air conditioners, and likewise switched to R-134a (HFC 134a) when the further production of R-12 was banned.

Depends on what type of AC system it is. Some AC systems use water, which, of course isn't. The ones which use HFC and CFC refrigerants (R12, R134a, R212, R22, etc.) are, however.
It's actually a gas, and it's known as refrigerant - depending on model year, it may be CFC-12 (R12) or HFC-134 (R134A). A lot of people call it Freon, but it's sort of a misnomer.. Freon is a trademark name by Dupont for a line of CFC and HFC refrigerants they manufactured, so it's not actually Freon unless Dupont made it and marketed it under that name.
Yes, some countries still use R12 and R22 refrigerants, although their usage is declining due to environmental regulations. R12, a chlorofluorocarbon (CFC), has been largely phased out globally under the Montreal Protocol due to its ozone-depleting potential. R22, a hydrochlorofluorocarbon (HCFC), is also being phased out, with many countries implementing timelines for its elimination. However, in certain regions with less stringent regulations or older equipment, these refrigerants may still be in use.
Define "older model". Up to the early 90s, they used R-12/CFC-12. Good luck trying to get that anymore. R414B is the recommended replacement for R12 systems.
