get gun shells, some are unknown to me — please help me

Hi guys,
I got many pods. I can not assign some.
I hope you can help with that.
Photo 1:
These are 3 different projectiles. Can you recognize which ones are? Middle is pointed bullet?
Why is the right ribbed?

Photo 2:
I did not find anything. Is that polte? German?

Photo 3:
What is E17? Manufacturer MF?

Photo 4:
This is France before the First World War. Correct?

Photo A, B, C:
That’s a big cartridge. 100 x 19? This is not a 20mm flak.
What was it used for? What does U 4 3 mean?

Other cartridges were built around 1920 in Czechoslovakia. The Czech and the French were found in a forest in Bavaria.
How do they get there? Did the Germans steal them in 1939 in Czechoslovakia?

I hope you can help me.
Thank you, love, Daniel.
