A severe thunderstorm watch means that general conditions in a region favor the formation of severe thunderstorms. It does not indicate any immediate threat. When a storm becomes severe or threatens to become so, a severe thunderstorm warning is issued.
Severe thunderstorms carry the risk for wind gusts to 58 mph or greater, hail 1" or larger in diameter, and tornadoes. Note, though, that if conditions are favorable for thunderstorms to produce tornadoes, a tornado watch is issued instead.
If a thunderstorm is capable of producing a tornado in the immediate future or if a tornado has been detected then a tornado warning is issued. If general conditions are favorable for tornadoes but there is not necessarily an immediate threat, then a tornado watch is issued.
A tornado watch is issued when general weather conditions in a region are favorable for the formation of tornadoes. Tornado watches are numbered in the order that they are issued. So tornado watch 4 is the 4th tornado watch issued in the country that year.

An active thunderstorm means that there is currently a thunderstorm in an area indicated. There is probably thunder, lightning, wind, and rain occurring when a thunderstorm is active.

Yes. A high-risk outlook does not need to be issued just on account of tornadoes. One case of a severe thunderstorm watch during a high-risk outlook came on June 12, 2013.
If a moderate risk of severe weather is issued there will almost certainly be severe thunderstorm watches or tornado watches issued.
No. That would be a severe thunderstorm watch. A severe thunderstorm warning means that a severe thunderstorm ha already formed.
If a thunderstorm is capable of producing a tornado in the immediate future or if a tornado has been detected then a tornado warning is issued. If general conditions are favorable for tornadoes but there is not necessarily an immediate threat, then a tornado watch is issued.

Stop trimming the tree; there's been a thunderstorm warning issued. The thunderstorm may bring strong winds and a lot of rain.
A tornado/thunderstorm watch means that weather conditions are good for tornado/thunderstorm. A tornado/thunderstorm warning, however, means that conditions are extreme and a thunderstorm or tornado is likely. Conditions for either storm are very good at this stage.
You can watch the skies for darkening clouds and lightning in the distance. The best way to know if a thunderstorm might be threatening is to watch the weather on television or the Internet.
