For starters, you'll get insufficient cooling from your system. Refrigerant changes states from liquid to vapor and back again in order to achieve cooling, and the system pressure is balanced to facilitate this - excessive refrigerant makes it much more difficult to do this. Additionally, your system will generate excessively high pressure, which will ultimately damage or destroy system components.
Why do you want to refill it is there a leak? It depends on the type of refrigerant and how much refrigerant will be needed. Check with 3 or 4 heating and cooling service establishments and get an average of what there charging in your area.

Not much, the excess coolant would be pushed out the overflow tube.
Usually there is no immediate result except for reduction in cooling proficiency. If the system is overcharged it will not cool properly, of course, this depends on how much over charging you are talking about. As more refrigerant is added the system's pressures will increase. At some point these pressures will become excessive and this will result in damage to the system usually over time. An A/C system is designed to run on a specific amount of refrigerant. Any deviation from this will cause less cooling ability.

The amount of freon in an air conditioning system is more dependant on the size of the components and the type of equipment than the cooling capacity. A typical system has a tag located near the charge ports that will tell you not only how much refrigerant is in the system, but what type as well.
First off, how many refrigerant refills have you done, and how frequently? If you're constantly having to replace refrigerant, you obviously have a leak. Other than that, there are a multitude of reasons an AC system can give insufficient cooling. A system performance test is necessary in order to narrow it down. Blockage in the system, compressor failure, compressor clutch failure, low pressure switch failure, excess refrigerant, insufficient refrigerant, inability of air to flow through the condenser fins due to damage or bent fins, bad accumulator, too much PAG oil, air or water contamination in the AC system... all are possible reasons why your AC isn't performing as expected.
How much refrigerant used to recharge the AC system in a Honda Civic depends on how much the system needs. There will be a gauge on the refill bottle which is tell the user how much is needed in that one application.
Probably the system is overcharged - too much refrigerant. Liquid refrigerant is boiling off as it enters the compressor inlet making it very cold. This can harm the compressor since liquid refrigerant is not compressable. It can also happen if the evaporator coil is blocked or plugged up with debris (on the air side).
about 10% to 15% of system charge
How much it takes, or how much it has in the system at any given time? To know how much refrigerant goes into the system, there'll be a sticker from the manufacturer - usually on the section of the HVAC compartment which extends under the hood. If this is faded or absent, the owner's manual should tell you. If that's unavailable, there are online resources. As for what's in your system at the moment, the only way to tell is to evacuate, recover, and weigh the refrigerant you have in your system.
