2. I think Netero still has a full coat of aura when using the Guanyin given that Razor didn't seem to be effected that way by his nen devils only his overall aura capacity was like when Morel uses his smoke troops or how Pitou expends nen to control her puppets I just lowers their max aura cap but doesn't take away their ability to utilize Ren.

4. From what we've seen I'm gonna have to say for movement speed it's Meruem, Pitou, Killua(Godspeed) then Cheetu, and Shoot flying... But in terms of combat effeciency I'd say Meruem, Killua and Netero are close, followed by Pitou, and Cheetu.
