If all you want to do is pass through Apple Remote commands to Plex, you don't need to use multiple remotes support in Remote Buddy. Instead, you can use the Virtual Remote to forward Apple Remote button presses to the OS X Apple Remote subsystem, from where Plex' helper can pick it up:

http://prntscr.com/539afc in the Plex behaviour only a few standard commands are represented and they are the same in all the virtual apple remotes
http://prntscr.com/539b6g this is how the mini harmony blog says the plex keymap should look, how do i get it in remote buddy?
If you want to implement that blog post's suggestions instead, you'd probably have to use the table you posted (http://prntscr.com/539b6g) and assign the actions according to that table.
F.ex. for "AR159 > Links" select the action "Red".
http://prntscr.com/539at9 In behaviours the Plex behaviour is empty is that correct?
Yes, since there are no options to be set for Plex as a whole. Take a look at the Behaviour options for the Virtual Mouse to see what options for a Behaviour look like.
The mapping of actions to buttons is configured in Prefs > Mapping.
