All right, let's finish this.
I think you missed Allan's answer for 5 & 9:
5 is a Boeing 737 C40-A Clipper and 9 is a Packard Clipper - Allan L.
Then, 41 is a Packard Hawk, and 29 a Curtiss F6C-3 Hawk
That leaves 14 and 24.
24 is the Pennsylvania Railroad locomotive designed by Raymond Loewy (graciously posing). It is known as the S-1 or 6100, so the car N° 14 should be the "something... S-1 or 6100".
I can't find anything with one of these names, but I think other guys here will be better at that.
