Yes. Particularly males. Females get along much better than males do, so it's wiser to keep a grou pf 3-4 females together.
Males should live alone, though you can have adult males with 3-4 week old baby boys. This creates a colony.
Only if their in a fight
No, but if they are male mice they will fight for dominance
They get into a fight or accident.

Their women, of course they fight.
other vats, they hunt for mice, they fight raccoons and badgers and hawks. (sometimes dogs)
No. They probably will fight.
It is very common for mice to fight especially males if they are not brothers. The most common reason for mice to start a fight it over food, you could have a bowl filled with sunflower seeds but they will fight over the sunflower seed the other one has. The best way to prevent another fight it to always be adding toys and moving things in the cage. To stop the fighting you can split them up for a week, then re intoduce them in the bathtube or a "neutral" space. Clean the cage and put them together again. Mice that live alone tend to get lonely and will miss their companion.
