Fellow ('21) V85 TT owner here.

I just got mine in May.
I'm no guzzi expert, but I know my way around an engine. Of course I could always be wrong. Here's what I think.
The top one marked #2 "Blow-by pipe" routes any gasses that blow by the piston rings into the intake. It also includes any gasses from the hot oil inside the crankcase Those gasses are no worry at all in the combustion chamber, and may actually be flammable and therefore "good" in the intake. In cars that's equivalent to the "CVS" or Crankcase Ventilation System. It prevents the crankcase from getting pressurized, and gets rid of those gasses in a sensible way.
https://en.wikipedia.org/wiki/Crankcase_ventilation_systemI think the others are also part of that system
, but we can't see the legend for #7 and #10.
EDIT: Yes, #7, #8, and #10 are also part of the blow-by pipe.
Are you able to post the document that you got the screenshot from? I'd love to have a copy of it for myself as well as to better address your question.EDIT: Don't unplug them. They're important!
By the way, can we see a pic of your bike? The V85 is so pretty.

EDIT: Here's mine:
