Jasta 18 'Raben' individual pilot insignia

Hello, I'm working on a Jasta 18 project and it's proven hard for me to assign the limited amount of known Jasta 18 planes to their respective pilots. I dont as of yet have "Fliegertruppe 1914-1918 Nr. 2", wich I've read would be a good help, so I've had to use the couple books I do have with some info. However, I did find several paintings, and model decal sheets online but I'm unclear as to wich pilot's planes are being depicted in the images I'm linking too, and if their even correct. If you could help me identify the correct pilot with their aircraft I'd apreciate it. Heres the image links;

The painting at the bottom of this page of the three DVII's shows Ltn Gunther von Buren's plane in the middle, but I'm unsure about the other two. The pilot of the top one I believe is still unkown by anybody but I could be wrong. The pilot of the bottom DVII with the three pointed star insignia is confusing for me since I think I've seen this insignia attributed to both Uffz Glatz and Ltn Heinz Kunster

This FCM Decals pic shows OfStv Wilhelm Kühne's DVII at the top, though it is unlabeled as such, and attributes the next DVII with the two verticle bars as that of Kunster, while the one below with the three pointed star is attributed to Glatz. The bottom one is Raben's DVII of course. However, what is confusing is that in this next FCM decals set pic;

they appear to completely reverse themselves and to label the top DVII with the two vertical bars as that of Glatz, and then attribute the DVII at the bottom with the three pointed star to Kunster... I dont know wich is right.

In this Barry Weekly painting, he shows Raben's DVII in the background, but I have no idea who the pilot of the 'death's head' DVII in the foreground is. I tried to look up if any pilots in Jasta 18 had previously served in one of the 'Death's Head' Hussar regiments but could'nt find any info, maybe the pilot just liked the image? Anyone know who this guy is?

Lastly, in this other Barry Weekly painting we see Raben's Dr.1 in the middle, but I am unsure of the identities of the two Albatros pilots next to him. If I know these pilots names I can see if they served in Jasta 18 at least into June when the unit started to get their first Fokker DVII's. Then I can only hypothesize whether or not they transfered their same insignia from their Albatros to their DVIIs, unless I get photographic evidence to confirm one way or another.

Thanks for any help you can give me!
