What is it? These are a mystery!

Recently my husband and I came across some very interesting items in a box. And for the past several weeks we have been looking to see if we see anything like these items. So now I am asking everyone in these pictures below which I will number (Just in case) if anyone has any possible solutions as to what these are or who a maker is or any information would be very helpful :) So here it goes, help me out :)
