On the older ones they take R-22 freon and on the newer ones with 410 Puron freon..........

No. The sale of R-22 freon is restricted in the united states because if it's effects on the environment. The only people who are allowed to purchase R-22 freon are certified refrigeration and air conditioning technicians. If this is for your vehicles, you can buy a converter kit at any auto parts store. This will allow you to use R-134a to recharge your car's air conditioning.
There is no freon in a home sprinkler system.
yes
r-22 (gentron), and r-410a (puron)
Air conditioning systems for structures don't use the same refrigerants as vehicle AC systems do. Your AC system probably uses R22.
It is advisable to call a technician to repair your air conditioning. He will solder the damaged pipe so that the freon wont leak anymore. Besides being dangerous, the lack of freon makes your air conditioner to work badly, and even stop refrigerating.
You should take it to a mechanic to have that done, it's usually not something you can do at home in your garage.
That would depend on where in the system the valve is. In many instances you can pump down the unit so all of the refrigerant is in the condenser and change a valve that is on the low side of the system or indoors.

it would be R-22.. brand new units will have the new refrigerant and that is R-410
