The first one is very much like Futura Bold.

It's not particularly a matc for your samples, ut to answer your second question I find the Gill sns family highly redolent of that era, generally pleasing a nd highly flexible in all its different weights and styles.

1. Neutraface from House Industries would be a good substitute

2, 3. Consider Franklin Gothic Extra Condensed, the condensed weights of Bureau Grot, Placard, Aurora Bold Condensed

they asked for free faces similar... neutra is far from free, but totally worth it if you can spend the cash.

First one is closer to Metro #2 Black or DH Sans Bold

For the second one, consider Univers 49 Light Ultra Condensed.

Third, Franklin Gothic Extra Condensed.

There's a condensed sans here that's both free and based on similar historical sources:
