We don't know all of the planets that are in the universe, only a very small amount. The hottest one in our solar system would be Venus.
The hottest exoplanet discovered as of March 10, 2008 is called "WASP-12b", and it's mean temperature is about 2240 Degrees C, or 4070 degrees F.

No. An exoplanet is a planet outside of our Solar System.
Both exoplanet and extrasolar planet are planets that are outside the solar sysytem.
No. A moon is not a planet. An exoplanet is aplanet that orbits a star other than the sun.
No. The nearest exoplanet is more than four light years. We cannot travel anywhere close to that distance
Exoplanet GJ 1214 b takes about 52.7 (+- 5.3 ) days to rotate on its axis.
We obviously don't know what the hottest exoplanet is but the highest estimated recording we have is of the planet HD 149026 b which is 2038 C or 3700 F
which exoplanet is 'THE exoplanet'?
The darkest exoplanet is "TRES-2B".
No. An exoplanet is a planet outside of our Solar System.
51 Pegasi itself isn't an exoplanet, it's a Sun-like Star. But it does have an Exoplanet orbiting it, 51 Pegasi b (informally named Bellerophon.).

Yes. While we know relatively little about the atmospheres of individual expolanets, there is no reason an exoplanet couldn't have an exosphere.
We do not know enough about conditions on any exoplanet to determine if any would be suitable for humans.
yes
extra-solar planet.
