Neverland is the second star to the right but, at the end of the movie, the ship travels to the first star to the left in the group of 2 stars.
The RAF fighters firing on the ship over London were flying far too slow, and they wouldn't have flown at night. Night time air defence was provided by anti-aircraft guns until radar-equipped night fighters became available - none of which were Spitfires or Hurricanes.
In the tribal village, lights are seen hanging in lines from tents and other places. There is no way these can be lit up because there is no way they can get electricity, and there is no evidence of any solar power.
What does anyone eat? No signs of any crops being grown. Nor of anything edible in the jungle.
A ship that is already in the air does not need sails. It would move with whatever air current there was. (OK, it is magic, but there still should be some logic.)
