In the book it doesn't say when all of the tributes die because most of them died on the first day
In a usual year, 23 out of 24 die, which makes it about 96% of the tributes.
24, two from each of the twelve districts.
The electric field that would throw them back on the roof is what prevents tributes from jumping. This is probably placed so that none of the tributes can commit suicide or escape before, or during, the games. The Capitol doesn't want tributes to die before the games so they can watch them die for entertainment, or need to get another tribute last minute.

Eleven tributes die on the first day of the hunger games: 1. The girl from district 3 2. The boy from district 4 3. The boy from district 5 4 - 5. Both tributes from district 6 6 - 7. Both tributes from district 7 8. The boy from district 8 9 - 10. Both tributes from district 9 11. The girl from district 10
She doesn't. She and Peeta spit them out. The Capitol tells them, the only remaining tributes, to kill each other and they refuse so they pretend to plan to kill each other and die together and then they win.
The Capitol basically picks people to fight in the arena, sends the tributes to them, train the tributes, sets up the arena, and watches them die.
She is scared of them because they each represent the dead tributes e.g. there is a huge dark brown one which represents Thresh and the muttations also each have the dead tributes eyes.
