1 like kurapike and the others they are bound to quickly find out about nen since a hutner license without being able to use nen is kind of useless in most jobs, also the hunter association keeps track of all those who pass the exam to see if they are learning about nen which is evident from Wing giving the nen status of all the others that passed along with Gon.

2 The man in charge Bounty Hunter seemed like a poser in the 2011 anime who just hired some strong people to do his work for him, most of them if not all of them most likely don't know about nen.

3 it might be for training as said before but also they are the highest and most powerful man of the entire worlds mafia, they most likely had protection and countless fighter and many of them with a wide array of nen abilities protecting them. It was most likely a strength in numbers kind of thing.

4 maybe he has an ability to imprison them in an object or alternative dimension this both would be cool and handy. In short I don't know.

5 like is said she didn't need to scan him he killed the previous one and they don't care

6 Phantom troupe obviously

7 Owl was tortured and eventually killed by Feitan.
