A little bit less than a train made out of paper, but way more than a boat made out of paper. Of course, the size of the airplane wasn't stated in the question. If it was a really, really BIG paper airplane, it could weigh more than a teeny-tiny paper train. Although, if it was a tiny paper airplane it could weigh less than a HUGE paper boat. I'm pretty sure it would also depend on what kind of paper you use. A construction paper airplane would definitely weigh more than a tissue paper airplane. But one of those airplanes made out of copier paper would weigh about average. I wouldn't reccommend a toilet paper airplane. It would also depend on what kind of plane you were making out of paper. A 747 made out of tar paper is going to completely outweigh a Cessna made out of freezer paper. All in all, I would have to say a medium sized airplane made out of a mid-gauge paper would weigh in at around 3,982 kilograms.

Well, if you want a certain TYPE of paper airplanes, and how many are there of that type, ask that. There is no real answer. A paper airplane is probably being made right now!
The design of a paper airplane determines its ability to perform certain stunts, as many planes are designed to be inherently stable.
Generally, this is a matter of individual preference. It is unlikely that one paper airplane design is the best at everything (range, speed, glide ratio, etc.). Many airplanes are claimed to be the best, but these claims are unsubstantiated.
Depends on its design limits.

The number of paper airplanes possible would be a function of their individual sizes. It could be one paper airplane, or many.
A paper airplane by ken Blackburn is the longest to stay aloftin 27.9 secs. but a walkalong glider flies long too but it is not a paper airplane because you still need to cut tape and fold.
That is approximately 15 grams.
It depends on the type and configuration of the aircraft.
