It must be checked by someone who knows what they are doing. There is no way for you to know.
you can press the pressure release valve until you have evacuated the refrigerant sufficient enough so that it won't be overcharged.
It means that you have a refrigerant leak, and will eventually lose all of your refrigerant. Then your AC won't offer any sufficient cooling, and if you run your AC with an inadequate amount of refrigerant, you'll eventually destroy your AC system. So it means that, if you don't want this to happen, you need to get the leak located and fixed. The presence of air in the AC system indicates a likelihood of a leak (or the leak) being on the low pressure (vacuum) side.

Well, we'd need to know what make, year, and model of car before that question can be answered. Not all automotive AC systems require the same amount of refrigerant.
To effectively replace AC refrigerant, follow these steps: 1. Turn off the AC unit and let it cool down. 2. Locate the refrigerant lines and valves. 3. Use a refrigerant recovery machine to remove the old refrigerant. 4. Connect a new refrigerant canister to the system and add the appropriate amount of refrigerant. 5. Check for leaks and ensure proper pressure levels. 6. Turn on the AC unit and test for proper cooling.
