Hello. Welcome.
What size are we looking at? Standard? 5/8-inch-ish?
Top right looks like a brick, which is great. Could be MF Christensen. Could be Akro. Leaning MFC.
Bottom right looks like an Alley.
Bottom left _could_ be Alley, or could be something more modern.
Not sure what to think about the other three. They look like ones which _could_ be modern, but looks like you have at least two nice old ones, so I don't want to jump to conclusions.
