I only have a guess for the first one...The back of a standing photo frame?
I could tell the first was a hinge but I didn't really know what on until I saw the comment above and I think she's right.2nd: deodorant, a cream, or a christmas ornamentIs the 3rd one part of a fan?The last one looks like frosty dead grass.
They're starting to get a little harder. You were right about the first one. The second one is deodorant. Then third is the crank to open my living room window and the last one is my wife's make-up brush.
