Many of these are from the Soviet Army.
The top ones (I'll mark them "A") are to show that the soldier serves in automobile brunch.
The ones with numbers (I'll mark them "B") show the classes of mastery (with 1 being the highest).
The star over the wings ("C") goes on top of a formal uniform cap if one serves in aviation.
The green star ("D") goes on a field cap (it would be red for everyday garrison life).
Below I provide an image (I found random ones on internet) so you can see their positions on the uniform.

And the lapel pin with the profile of Lenin is an award for an outstanding effort/achievement at (civil) work. It says "Leader of Communist Labor". It usually came with a certificate and increase in salary.
