Cyclone is the most general of these terms. It describes virtually any broad scale low pressure system of which a hurricane is one variety. Tornado, funnel cloud, and hurricane describe much more specific events.
A cyclone is more closely related to a hurricane. A cyclone is a general term used to describe a rotating low-pressure weather system, which can develop into hurricanes, typhoons, or tropical cyclones depending on the region. Tornadoes, on the other hand, form in severe thunderstorms and are characterized by a twisting, funnel-shaped cloud extending from the sky to the ground.
tornado clouds
A hurricane typically covers a larger ground surface area than a tornado. Hurricanes are large, swirling storms that can span hundreds of miles and affect large portions of coastal regions, while tornadoes are smaller, more localized funnel clouds that typically cover a few miles at most.
The barometric pressure at a tornado is very low, just like in a hurricane. It is also believed that many tornadoes have a relatively calm center where ari descends. This is similar to the eye of a hurricane.
A tornado is a narrow funnel of air that extends down from a cumulonimbus cloud, usually associated with severe thunderstorms.

Not sure what you mean by a funnel tornado. If you are referring to the Seymour, Texas tornado of April 10, 1979, it had a well-defined funnel and it was funnel-shaped. However, it did touch down so it was not merely a funnel cloud.
tornado clouds
A tornado that does not touch the ground is a funnel cloud.
Not technically. It is the beginning of a tornado, but they are categorized differently. It is not considered a tornado until it reaches the ground with damaging winds.
A funnel cloud that touches the ground is commonly known as a tornado.
A funnel cloud is a developing tornado that has not reached the ground.
A funnel cloud is like a tornado only it does not reach the ground.
The "eye" of a tornado is at the center of the funnel.
A tornado starts out as a funnel cloud.
To some extent, yes. A funnel cloud is the visible portion of a tornado. However, not all funnel clouds are tornadoes. If the winds associated with a funnel cloud do not reach the ground then it is not a tornado. Conversely, if the winds do reach the ground the term funnel cloud is not usually used, and the event is simply called a tornado.
In a sense, yes. But the term funnel cloud usually means a "tornado" that has not touched down.
