Are these tinnies?

Really, that's the question! I just bought a small lot of German items that included several tinnies with some other pieces mixed in. Can anyone clue me in these pieces?
Left to right...
"DDA" or "DDR", stamped and really is tin I think?
1914 on the front and hallmarked but can't read it. Maybe French?
Looks like a sea mine, unmarked, gnurled pin.
Bomb? Unmarked.
1786-1936 on the obverse, German construction. No marks.
Thanks guys!

the first is a VDA tinnie, the second I don't know and the other three are WHW tinies (donation receipts). At least I think the Alter Fritz badge was issued by the WHW? Cheers, Torsten.

actually I think the second tinnie is Swiss and was issued to mark the Swiss national day...there was a different one of these tinnies for every year for most of the last century...I am sure I have seen it before...has the flag got a big cross in the middle? I think the maker should be either Lusanne or Luzern based>? Cheers, Torsten.

Poop... I have always thought that the mine pin in my collection was a tradition pin!

Time to move it out of the tradition pins display, I suppose...
