A multiple vortex tornado may appear to consist of several smaller tornadoes which usually don't last more than a few seconds each. However, often the suction vortices may be hidden withing the main funnel. See the links for videos of tornadoes with visible suction vortices.

Not really, there is a such thing as a multiple vortex tornado. These tornadoes have smaller, stronger vorticies moving around inside of the tornado. Sometimes a multivortex tornado can have the appearance of being two or more tornadoes but it still is one tornado.
it depends on what the radar is measuring, but usually it will look something like an animal cell, with the tornado being the nucleus.
The worst tornado that is known to have been multiple vortex was the Tri-State tornado of March 18 1925. This was the worst tornado in U.S. history with a death toll of 695. At certain points along its path it was observed to have two or three funnels.
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.
The appears to be asking about multiple vortex tornadoes. The process of how a tornado becomes multiple vortex is called vortex breakdown. Thi occurs when the wind in a tornado is spinning so fast that it cannot reach the center. The low pressure instead draws air down the middle. This causes the tornado to expand. When the downward moving air reaches the ground it spreads out. Complex interactions between this outward moving air and air flowing into the tornado leads to the formation of smaller vortices within the tornado.
A tornado
This depends on how powerful the tornado was.
A multivortex or multiple vortex tornado is a tornado that has multiple suction vortices or subvorticies inside the main circulation. These short-lived vorticies are more intense than the rest of the tornado, sometimes packing wind up to 100 mph faster than the main circulation. Although the subvorticies are often obscured by the main funnel they sometimes show themselves as multiple funnels moving around a common center. It is still one tornado, however, even though it may look like two or more.
It would depend on the severity of the tornado.
The eye of a tornado is extremely calm and bears no resemblence to all the mayhem that the tornado causes to the outside world.
a funnel
A tornado looks either looks tall and skiny, short and fat,or medium sized.
Without a funnel, a tornado will likely appear as a whirling cloud of dust or debris. If there is not enough of that present, then the tornado will be invisible.

A tornado is a kind of vortex. Air in a tornado rotates rapidly. Additionally, a tornado may contain multiple smaller vortices.
Suction vorticies as smaller columns of rotating air within a tornado. They have more intense winds than the rest of the tornado. The suction vortices sometimes look like "mini tornadoes" moving around inside the main circulation.
Tornadoes come in different shapes, and the shape changes during the life of the tornado. Some tornadoes are like thin tubes or ropes, some look like large wedges. If it is wrapped in rain, or there isn't enough light, it can be hard to see a tornado. Sometimes clouds may look like a tornado but aren't, so looking for other clues like rotation is important.
