Finally got around to post my unknowns from Germany

Bottom is a button. But don't know age or design?

The easiest perhaps is the Red Cross pin: WWII GERMAN BADGES AND MEDALS PRICE GUIDE - MilitaryItems.com

 

[yaxthri]

The badge is a pin for an assisting nurse ("Schwesternhelferin") in the German Red Cross ("Deutsches Rotes Kreuz"). It's from WW2 as you can surmise by the swastika...
Can't help with the other two. #2 maybe a medieval lice-comb? Hahaha

 

[nhbenz]

Mustache comb I think.

I hope it's for a mustache rather than medieval lice lol
