Tokens, The camera in the first couple of pics would use either 120 or 220 size/type film. You can still find the film on e-bay and in good camera shops that still do business with film professionals (not Ritz or Wolf). I'm pretty sure it's 120 - I have a few Kodak Star-Mite models in my collection and that's what I've always used. With the exception of the flash working properly (yes, you can still find the bulbs for them), everything is mechanical on that camera (no batteries needed to actually snap a picture) so you can still use it once you find the film. As for the Polaroid, you can still find the film for these as well. It's a bit pricier than "standard" type film and you will probably run into the problem of the colors being off. Sometimes just a little, other times - WAY off (although at times, it can be a cool effect). Usually, the older the film, the more pronounced the problem.
As far as value goes, if it has all the pieces to it's "kit", the "Golden Shield" should sell anywhere between $10 and $25. I've never heard of that particular brand, but I'm sure there's someone out there that collects them. The Polaroid is about the same. Unless it was a very old model or one of the rarer colors, the value is about the same.
Regardless, they're both neat pieces to put on display, especially if your big into photography and such.
