I don't know the first, sure someone will school me, but the second and third are (2) Monark and (3) Hawthorne respectively .

I think the first is an Elgin?

The first one looks like an earlier Hawthorne to me. I think Elgins may have had a similar design, but the diamond pattern was large-small-large instead of equal sized diamonds. Unless both bikes were sourced from the same manufacturer at some point?
