Identity and authenticity 2

.
I believe that I know what these visor cap insignia are, except the roundels, but I would like those who are much more knowledgeable than me to confirm their identity and authenticity. Your help would be appreciated.

3. Wehrmacht Cap insignia (for in the cockade).
4. I would take a hazardous guess this is actually a Bundeswehr cockade, postwar.
5. RAD Cap insignia.
6-8. Cockades for the Kyffhauserbund-visors.

Please correct me if I'm wrong
