Sorry I haven'r seen you comment.
As per your 1st question - I don't know that since I've only tried using
3 screens in 16.04, prior to that I had a desktop setup (11.04 to 14.04)
with 2 screens without any problems, either using the nvidia drivers
either the nouveau.
Regarding the nvidia propertiary drivers they don't work for me at all. Even
when I did manage make them work the mini-display port didn't work so I could
use only the screen in the HDMI port and the build-in screen.
Only when I'm using the nouveau driver I'm able to use all the 3 screens
together but with that annoying issue.
