there is really no difference between how long cold water and warm water fish live. It all depends on the size of the fish. If you have a 1-3 inch fish it should live for 2-3 years. If you have a 4-7 inch fish it should live for 4-6 years. If you have a 7-10 inch fish it should live for 7-11 years and finally if you have a 10-15 inch fish it should live for 12-17 years. But dont forget that fish get sick. so if you have an 8 inch fish and it lives for only 1 year it either got sick or you didn't provide proper care for it.
Not in its full sense. Warm water fish will cease to live but cold water fish will slow down almost to the point of hibernation. As long as it does not freeze solid or happens to quickly cold water fish such as koi can usually survive.
Fish move slower in cold water as it slows down their metabolism to allow them to reserve as much energy as they can for the long term. This is the case for Koi for example if they are in a pond and live in a climate where ice forms on the top.

Well, that depends on what type of fish they are. Just like fresh water fish cannot survive in salt water, fish which had lived in hot water cannot live in cold water.
Fish are cold blooded, so yes. Cold blooded (ectotherms) animals have ways to survive colder environments such as slowing heart rate to preserve nutrients that the organism can use over long periods of time, or barely moving.
