  working in Latte I had to understand how Plasma is working with screens, it might help you to understand it...
  
  There is a **plasma-workspace/app/screenpool.h** class which is responsible for the ids you are mentioning.
  This class keeps a record the creates a table which is:
  ScreenName=id (e.g. 1,2,3,4, ... etc.)
  
  That table can be found at **~/.config/plasmashellrc** e.g.:
  
    [ScreenConnectors]
    0=HDMI-1
    1=eDP-1
    2=eDP-1-unknown
    3=eDP-1-1
    4=:0.0
    5=Screen26
    6=Screen36
  
  screenpool class is responsible to maintain that table and also to inform applets, containments, coronas etc for
  associations between ids and screens
  
  the Corona class has a **screenForContainment()** function that helps at that communication between applets<->screens
  
  screen() and lastScreen() : functions usually return the id of the screen based on ScreenConnectors
