That's a perfect example of the difference between boys and girls. The girl's bike is original and in good condition. No scuffs on the seat, it was never thrown down when done riding. Even has the original plastic basket. From the 60's.
The boy's has mismatched rims, replacement seat, and a bent fork. Fenders and chain guard gone too. But it's a keeper, as Kingfish said, a Newsboy Special. Looks like good tires. I had a 55 frame that I sold and later became a build here, the Pepperbox Special several years back by Missing Link.

Those frames weren't changed much over the years. The serial number will give you the year, it is lightly stamped on the left rear dropout by the rear axle. The first letter and numbers will ID the year.
not sure what brand the boys is, but it’s early.
