Top right one reminds me of the Eastern Alliance cruiser from 1978 Battlestar Galactica episodes (Season 1, Episode 19, "Experiment in Terra") - maybe even flipped upside down or had its nose chopped off.

Note, however, that modelmakers routinely kit bash (even digitally in these days of the computer) (Kit bashing is a practice whereby a new scale model is created by taking pieces out of other model kits) to get their models for filming, some more so than others: and some just keeping in line with what's been established in the film already (RV's with wings, etc); and some could just be keeping up with the humor, and in-jokes (probably what the classic flying saucer is - I did hope it was the saucer from the classic "The Invaders" (a Quinn Martin production!) but the windows are wrong), so could be nods but also could be anything. (That shuttle looks like its cockpit has been bashed up)
