Can you help ID these tiny things?

I'm going through my first purchase and have a few mysteries. The lot weighed about 11 pounds and had many manuals - mostly police stuff, ninjago, star wars, pirates... I've been able to almost complete a bunch of sets although the city sets are not close to being complete. After sorting and bagging what I could, I'm left with a lot of stuff. These are the pieces I'm trying to ID now. Especially that green thing - is it even lego?? thanks for any help you can give this newbie!!
