It becomes a tornado, obviously.
To be classified as a tornado, a funnel cloud must make contact with the ground. Once the funnel cloud touches the ground, it becomes a tornado and is classified based on its size, intensity, and associated damage.
A "double tornado" is scientifically known as a multiple vortex or multivortex tornado. In such tornadoes smaller vortices form within the main vortex of the tornado. These subvortices usually do not last long and individually do not impact the overall tornado very much. Rather than indicating a lack of organization in the tornado, a multivortex structure usually indicates a strong tornado.
When two tornadoes merge, they can create a larger and more destructive tornado. The combined forces of the two tornadoes can result in increased wind speeds and damage along a wider path. This phenomenon is known as a tornado outbreak.
Placing a marble in a tornado in a bottle will just act as another object caught in the vortex created inside the bottle. It will spin around with the other air and debris, but won't have any significant impact on the overall behavior of the tornado.
Tornadoes and lightning can occur simultaneously during severe thunderstorms. If a tornado and lightning occur at the same time, the combination can increase the potential dangers and risks associated with the storm. Lightning can strike the tornado itself or nearby, causing additional hazards like fires, property damage, and injuries.

Funnel clouds form when a tornado or developing tornado pulls in moist air. As the air is pulled inward it experiences a pressure drop which cools it to the point that the moisture condenses. For how tornadoes form see the link below.
Sometimes, but not always. In a typical situation you will see a low-hanging cloud beneath a thunderstorm called a wall cloud. As the circulation of the tornado develops, a smaller rotating cloud called a funnel cloud will develop in the wall cloud and extend toward the ground. If the funnel cloud reaches the ground or if there is a whirl of dust beneath the funnel cloud, then the tornado has touched down. This is the classic depiction, however, it does not always happen this way. In many cases, the area where the tornado is forming is obscured by rain. If the air beneath a thunderstorm is dry, the the tornado may develop without a visible funnel. Finally, many tornadoes occur at night, when it is too dark to see them.
A wall cloud will form and the cloud might build up a funnel!
In some cases one tornado will dissipate completely, and then a completely new tornado will form afterward from the same thunderstorm. This is called a tornado family.
Nothing special. All tornadoes stretch from cloud base to the ground. If the vortex doesn't reach cloud base or the ground it isn't a tornado.
It is a tornado BUT it is funnel shaped NOT an "inverted funnel" The other rotating destructive wind phenomena is not part of a storm (they usually happen on clear, hot days) and is called a whirlwind.
A tornado can hit a house, but cannot happen indoors.
Not exactly. If a tornado is imminent then Doppler radar will probably detect the rotation wand a warning will be issued that a tornado may soon form. Often, especially with areas of major damage, the tornado has already been on the ground for at least a few minutes and moves into the area. Meteorologists can often detect the signature of a tornado on radar will announce where the tornado is and where it is going.
There are two main factors. First, moisture in the air condenses as a result of decompression inside a tornado, producing the visible funnel cloud. Second, a tornado's winds lift dirt and debris into the air, forming a debris cloud or dust whirl
Sometimes a strong tornado will produce a weaker satellited tornado that orbits the main funnel, but other than that no. Tornadoes are essentially an end product to various weather processes rather than a cause. Tornadoes may be accompanied by hail, flooding, and damaging straight line winds, but these happen alongside the tornado and are not caused by it.
There is not such thing as a "chemical tornado" a tornado is the result of thermodynamic physical processes.
