I'd take 1,3 and 4 from your list. There's a lot of planes in the sky with the same basic size and shape of the 737, though the 73 has definitely by far made the biggest contribution to commercial air travel. Really the only thing that visually differentiates it for me is the flattened engine cowl.
As for #5, damn kids don't remember those planes. They may recognize it, but can't name it. Maybe replace it with the F-14.
