It depends on what you mean by "hornet." There are many species of wasps called "hornets." Even those considered "true hornets" by scientists comprise more than 20 species.
Even the simplest answer has to be "yes and no." In temperate zones, most hornets die before winter. Only the fertilized queens live in a dormant state until the next spring, when the begin building a new colony.
In warmer areas, hornets can live year-round.
I've found white-faced hornets hibernating under rotten logs. There were about four or five of them together. Scientific sources suggest that only the queen should be hibernating alone, but I found a number of them hibernating together!
If you disturb a wasp nest during hibernation, the wasps may become agitated and could potentially awaken from their dormant state. This could lead to them becoming defensive and attacking in order to protect their nest. It is best to avoid disturbing a wasp nest in any state, but especially during hibernation when disrupting their slumber could trigger a defensive response.
Yes, winter frost can kill a wasp nest by freezing and destroying the wasps inside. Cold temperatures can also prevent the wasps from being active and foraging for food, leading to the eventual demise of the nest.
Destroying a wasp nest typically results in the death of most, if not all, of the wasps inside. Wasps are territorial creatures, so destroying their nest could lead to them rebuilding elsewhere or looking for a new area to nest.
Most wasps are active during the day and rest at night. However, some species of wasps may be active at night, making them partially nocturnal. The behavior can vary depending on the species and their nesting habits.

Wasps all die in the winter except for the queens who hibernate (usually underground) and restart the colony in the spring.

Yes, the queen will over-winter in the nest with her workers. It is the males (drones) that may be kicked out to preserve food supplies over winter.

You get stung...
bees wasps build nest anywhere they can find shelter.

Wasps do not reuse old nests, so if you know the wasps have gone there is no risk and you can simply remove the nest.
It is possible for a new queen wasp to build a new nest next to or even attached to an old disused nest, however this will be a completely new colony.
There should be no danger of that. Only newly-mated queen hornets and wasps hibernate through the winter -- and they don't hibernate in the old nest. If there has been cold weather, especially if cold enough for a frost, the rest of the colony should have died.
