I was going to ignore this, but finally decided to take a crack at
it. I think I have most of them right.

01] How long did the Hundred Years War last?

About 116 years off and on, 1337-1453

[02] What was New Mexico named after?

I give my answer with some trepidation, since it seems to lack the
irony inherent in the others, but as far as I can determine it was
named after (Old) Mexico, which ceded the New Mexico territory to the
USA in 1848.

[03] Which country makes most Panama Hats?

Ecuador

[04] In the story "1001 Arabian nights" what nationality was Aladdin?

Interesting - checking Richard Francis Burton's translation of
"Arabian Nights" (first published in the 1880s), I can find no
character named Aladdin. The closest match is Ala al-Din, son of Cairo
merchant Shams al-Din, but his story does not seem to involve genies
from magic lamps.
BTW, this question is phrased incorrectly; the "Arabian Nights" is
not _a_ story, but a collection of several hundred stories.

German

[10] What is a Camel hair brush made of?

[21] A man travels due south for one kilometer. He turns left
90 degrees and travels due east for one kilometer, at
which point he shoots a bear. He then turns left 90
degrees and travels due north for one kilometer, returning
to the exact spot he left from.

The man starts at the North Pole, from which all directions are
south. The bear is a white polar bear. The described itinerary is also
possible starting from a point very near the South Pole, but there are
no bears there.
