How a tornado ends is not fully understood. It is thought, however, that cold air coming out of a thunderstorm (called outflow) undercuts the mesocyclone, the rotating updraft that drives the tornado. This chokes off the supply of warm air that feeds the updraft.
until the tornado ends and then the people fall and die or get injured
tornado
There is no such word as I am aware. For words that end in "r," a tornado may informally be called a twister. Some people call tornadoes cyclones, but this is technically incorrect.
If you mean to ask if one tornado can form after another has dissipated, yes. Supercells, the storms most likely to produce tornadoes, often go through cycles. They can spawn can spawn multiple tornadoes one after another in what is called a tornado family. Sometimes the next tornado in the family will form before the current one has dissipated, resulting in there being two tornadoes at the same time.
Tornado season begins in March and ends in July. April is historically the deadliest month, although May has more tornadoes. However, tornadoes hit the U.s. in all months. Tornado season is simply more active.
If you mean to say to tornadoes take away everything they touch, no. Some stuff they leave in place depending on how strong the tornado is. If you mean to ask if everything a tornado picks up stays with the tornado or ends up back where it started, then the answer is neither. When a tornado picks something up it will stay airborne for a bit but will eventually fall back down somewhere else or end up stuck in something such as a tree or a wall.
tornado in Portuguese is tornado too
No, it is not possible to stop a tornado with another tornado. Tornadoes are formed by specific weather conditions in the atmosphere, and introducing another tornado would not have any effect on the existing tornado.

No, a tornado watch is issued when the general weather conditions can produces tornadoes. If a tornado is spotted a tornado warning is issued.
