A partial or nearly complete blockage would be my guess. have a plumber snake it out or it will just get worse. You might want to buy and use a closet augur first as the blockage could be in the toilet trap itself. It's easy to do and is cheap as a first course of action. If in doubt call rotorooter or your local (trusted)plumber
Depends on if it needed to be flushed or not.
Yes you can flush it. It's possible for a toilet trap to go dry after that much time. When you flush just make sure you check to see if the bowl is leaking.
All of it if you don't flush or if it doesn't leak.
The toilet overflows when flushed because there is a blockage in the drain pipe, excessive water pressure, or a malfunctioning float mechanism in the tank that allows too much water to enter.

3 to 4 gallons. They want to reduce this to about 1.3 gal.
An old style (pre 1990) toilet uses 13.5 litres. The newer 'low flush' toilets use 6 litres or less.

Alot more than it would to fill your toilet
A toilet overflows when there is a blockage in the pipes or when too much water is flushed at once. To prevent this, avoid flushing large amounts of toilet paper or foreign objects. Regular maintenance, such as using a plunger or drain cleaner, can help prevent blockages.
Toilets can clog frequently due to a variety of reasons, such as flushing non-flushable items, using too much toilet paper, or having a low-flow toilet that may not have enough flushing power. It is important to be mindful of what is being flushed and consider upgrading to a more powerful toilet if necessary.
