Thanks all to those who replied so far! I should mention that mom's is a merle; which is a dominant trait; the pups are all double merle (mostly white) except for Leon who is just a standard solid merle. So, color-wise I know that won't be any indication since they got that from mom. Their coats are longer, and they have longer fur on their muzzles as well; and a few folks thought they had yorkie-er head shapes & eyes than a Chi. Again thanks for responding and I look forward to seeing what anyone else says! =D
ETA: Oh, and here's an old pic of a white "just chihuahua" long haired pup at the same age, he came from the only other litter of pups I've helped raise and his mom is still here today too. =) This kinda shows better how much shorter fur even the 'long haired' Chi's have.
