Not very long. Neptune is made of Hydrogen and helium. So you can't breath.

Neptune is always outside the asteroid belt
There have been no space shuttle landings on Neptune. It would be impossible to land on Neptune for two reasons: 1 - Neptune is a gas giant 2 - Neptune is freezing cold, electronic equipment would freeze and malfunction
It may be possible in the future, but today we are not able to travel that far.
Considering that no human has been to Mars, so far, it seems a bit premature to talk about sending someone to the far more distant planet Neptune. However, the technology of space travel does exist (as proved by the 1969 moon landing) and if we were willing to spend the very large amount of money needed to build an interplanetary spaceship and to launch the mission, it is possible for a human to travel to Neptune. I will add that Neptune itself is not the kind of planet on which a human could land - it is a gas giant, made mostly of gas - but the moons of Neptune would be interesting to visit.
No, Neptune does not have human or human made objects. It is to cold on Neptune so therefore, nobody has ever been on Neptune.
Techinically, Forever. But, we don't know that Neptune exists, so we can't say for sure.
