The reference I'm using here is an extract from Abschnitt IV of the 'Anzugsordnung für das Führerkorps der HJ (E. FAO) dated 15.5.1937'. The references listed in the order are:
Gesetz über Titel, Orden und
Ehrenzeichen dated 7.4.1933
Verordnung zur Ausführung des Gesetzes über Titel, Orden und Ehrenzeichen dated 14.11.1934
Verordnung zur Ausführung des Gesetzes über Titel, Orden und Ehrenzeichen dated 17.3.1936
Verordnung zur Änderung der Verordnung zur Ausführung des Gesetzes über Titel, Orden und Ehrenzeichen dated 17.3.1936
Anordnung number 139/36 from the Stellvertreter des Führers dated 6.11.1936 on 'The wearing of Medals, honour badges and badges'.
Anordnung 9/37 from the Stellvertreter des Führers dated 12.1.1937 concerning the authority to wear the movement's honour badges.
This is all taken directly from a 1942
book which means that all laws and regulations mentioned were still valid at that point. With that in mind I think that we can assume that it was valid until the end of the war.
Further information comes from "Aufbau und Abzeichen der HJ" 1940
For the HJ there is only one HJ tinnie (Tagungsabzeichen) listed which was elevated to national honour status and that is the
Potsdam badge. From 15.5.1937 only the silver version was permitted for wear. Also, all other tinnies including WHW were only permitted to be worn for the duration of the event. This applied to all branches of the Hitler Youth.
HJ and DJ:
Sport badges.
Only two sports badges were permitted to be worn at the same time. One of them had to be the
achievement badge (if the person had qualified of course) and the other could be chosen freely from the following list.
SA sports badge
Deutsches Reichssportabzeichen (including the earlier Deutsche Turn- and Sportabeichen)
HJ
Leistungsabzeichen (only the highest level awarded was worn)
HJ
shooting badge (as above)
Reichsjugendsportabzeichen
Jungfliegersportabzeichen
Deutsches Reitsportabzeichen
Deutsches Fahrerabzeichen
Deutsches Jugendreitabzeichen
NSKK Sportabzeichen
Meisterschaftsabzeichen of the Reichsbund für Leibesübungen
Ehrenzeichen für Verdienste um die Plege der Leibesübungen
Achievement badges were worn on the right breast pocket (the second sports badge from the above list was worn to the right of the party badge and
HJ-Ehrenzeichen/HJ membership badge on the left breast pocket).
Shooting badges were worn on the right breast pocket
The Potsdam badge was worn below any sports badges on the left breast pocket
The HJ Ehrenzeichen was worn on the left pocket flap.
The party badge was worn directly below the HJ-Ehrenzeichen.
BDM/JM:
Only the following were permitted:
HJ membership badge or
HJ Honour badge
Party badge (for party members)
Achievement badge
Potsdam badge
The HJ-Ehrenzeichen (or normal membership badge) was worn centrally on the left breast pocket. Directly below that was the party badge.
On the blouse the achievement badge was worn on the left breast pocket between the buttons (on the Kletterjacke on the left breast pocket to the right of the button)
The Potsdam badge was worn to the right of the HJ-Ehrenzeichen on the left breast pocket.
If there's anything else you need to know just give me a shout. What I have quoted above are the regulations and so this is how badges were ordered to be worn. In reality we sometimes see deviations from this on photos but that doesn't mean that the person depicted was doing things correctly
