My mom collects antique dolls. They look like Bisque dolls to me. They are probably 40s by the look of the heads and the clothes. Do they have any markings on them anywhere? Sometimes they have marks(a maker's mark - a circle with a letter in it or a crown or something similar) on them especially ones that are made of porcelain. If I get a chance I will ask her to look at your picture and she may be able to tell you more. She has been an antique collector all her adult life and loves the dolls.
The one that opens and closes it's eyes could be made in the 50s. I have one very similar and it's eyes also open and close.
