The first 2 "I don't knows" look like anvil tools for a pritchel hole or for a vise hole. What is the diameter of the base shaft? I have a thing for hardie's and pritchel hole tools.
The week before last I bought a flat of stuff because I saw a vise with what looked like a pritchel hole tool. My son was helping unload everything into the garage & I told him the only tools I wanted to bring in were the vise, what looked like a large tap handle with 2 holders, and the box with 8 vintage woodwork planes in it. He brought the vise in, I grabbed the tool out of its hole & told him I didnt care about the rest of the vise for now. He made a face, but I am not sure if it was because I was rude for making him carry the vise an extra 50 ft, or if he was scheming on the vise that I hardly looked st. Probably both. The tool was too big for the pritchel hole on my little 35 lb anvil.
Alternatively they could be punches or alignment for some other tool. I'd try a small file on it to see how hard it is.
