Hi! Super cool! thanks for sharing! This is really cool! I think I can help a tiny bit here.
In the first picture . . .
The second one (stick pin) is an Army Regimental pin. See this link for info about the regiment:
The third one is a Swedish Army Ski Troops qualification badge.
In the second picture . . . I don't know what the first one is, although is is super cool and I could think of things to do with it! -grin-
The second one is a crown with two entwined Gs and a V in the center. This is for Swedish King Gustav V. He reigned from 1907 until his death in 1950. Your picture is really blurry, but if I could see the scroll detail, could probably figure out what it was for in particular.
The third one is for King Gustav VI Adolf, King Gustav V's son. The scroll says 11/11 1952 - this was for his 70th birthday. Interesting trivia, he was the longest waiting heir apparent until Prince Charles broke the record recently.
The fourth pin is a fraternity pin.
