Well done!
Some minor suggestions - for grammatical correctness:
First document:
Im Namen d
es Führer
s...
"dem" is doubled - keep the printed one.
Second document:
"Aufgrund" - one word (today "Auf Grund" is possible, but it wasn't in the `40ies) - "due to/on the basis of"
"Ermächt
igung" - one word - "authorization"
Fourth document:
"das Ritterkreuz
des Eiserenen Kreuzes"
Fifth document:
"
das Eichenlaub zum Ritterkreuz
des Eisernen Kreuzes"

The real one - not only the "provisonal ownership certificate" (vorläufiges Besitzzeugnis)
