Yes. Tornadoes need thunderstorms to form.
Hail forms in the strong updraft of a severe thunderstorm, which keeps the hailstones airborne as they form. Tornadoes require a specific type of severe thunderstorm called a supercell. The tornado itself forms from a strong, rotating updraft which can also generate hail.
They form they same way as other tornadoes do. See the link below for information on how tornadoes form in general.
In a few cases there have been as many as 13 tornadoes on the ground at the same time in different locations.
Most tornadoes originate within a rotating mass of air in a thunderstorm called a mesocyclone. Under the right conditions, a downdraft can wrap around the mesocyclone, causing the circulation to tighten and intensify, while at the same time stretching toward the ground.
When the relative humidity and dew point temperature are the same they form clouds.
Yes. The thunderstorm is actually what produces the tornado.
True
To a point, yes. Storms that develop tornadoes are much more powerful and lower pressure than a "normal" thunderstorm, but both forms could be classified as a thunderstorm.
Not really. A tornado is a specific type of storm. So a tornado is a storm, but most storms are not tornadoes. A tornado is a violently rotating column of air extending from the base of a thunderstorm to the ground often made visible by a funnel cloud.

Not only, that. The thunderstorm is what produces the tornado.
A twister, more commonly called a tornado, is a violent, rotating windstorm that can develop during a severe thunderstorm. Compared to other types of storm tornadoes are small but incredibly violent. Tornadoes are usually made visible by a funnel or cone-shaped cloud and often produce a swirling cloud of dust and debris that they pick up from the ground. Tornadoes can range in size from a few yards (meters) to more than 2 miles (3 km) wide and in the worst cases can produce winds in excess of 300 mph (480 km/h).
No. Tornadoes and hurricanes form in completely different ways and operate on different scales. In very simple terms, hurricanes form when clusters of storms over tropical oceans gains strength and form an organized, large scale and violent storm system. Tornadoes form when rotation within an individual thunderstorm tightens and intensifies into a small-scale but very violent whirlwind.
Tornadoes form in the southern hemisphere for the same reason they form in the northern hemisphere. The mechanics are the same. See the related question for what causes tornadoes
Large hail, flooding, straight line winds and tornadoes.
They form they same way as other tornadoes do. See the link below for information on how tornadoes form in general.
How do tornadoes dissipate? The details are still debated by tornado scientists. We do know tornadoes need a source of instability (heat, moisture, etc.) and a larger-scale property of rotation (vorticity) to keep going. There are a lot of processes around a thunderstorm which can possibly rob the area around a tornado of either instability or vorticity. One is relatively cold outflow -- the flow of wind out of the precipitation area of a shower or thunderstorm. Many tornadoes have been observed to go away soon after being hit by outflow. For decades, storm observers have documented the death of numerous tornadoes when their parent circulations ( mesocyclones) weaken after they become wrapped in outflow air -- either from the same thunderstorm or a different one. The irony is that some kinds of thunderstorm outflow may help to cause tornadoes, while other forms of outflow may kill tornadoes.
