You're never going to find the maker of these. Even if you did, it wouldn't add much value, so just sell them on theri own merits.
They're not exactly Hummel knock-offs (although the Japanese did many such), but they're vaguely based on Hummel figurines. They date from the 1950s-'60s and were popular items in Woolworth's, Murphy's, and other dime stores.
