I also think that a number of those figures you have pictured at your site and listed as Vintage, are actually some very current items that the Star Traders stores have been selling over the last several years (Chewie, Vader, Stormtrooper, Yoda). I think they're just some cheap little "bendy" figures. I've seen some very similar to these for sale in Disneyland. I'll check to see if they've still got them in stock tomorrow when I'm there...
As for the company...I don't know, but I'd guess it's either Hasbro (or formerly Kenner) or Disney who makes them.
