My thoughts aren't totally organized for this response, so I'm not sure where the best starting point is, so here goes. First off, in Kenyan sand boas, there are two types of albino traits. The first is the standard amelanism that is common in many species. The second type is the paradox albino. This trait is an amelanistic mutation that also causes the animal to have black splotches. These two are incompatible, but both are simple recessive traits. The other common morph in KSB's is anerythrism, such is your male in the bottom picture.
Snow, on the other hand, is not a single simple recessive trait. Snow is a combination of anerythrism and one of the two albino traits. Standard "snow" is an animal that is homogenous for albino and anery. "Paradox snow" is an animal that is homogenous for paradox albino and anery. Something to note is that if an animal is marketed as "het snow" is usually means that it is anery and het albino or albino and het for anery. The same technique applies to paradox snow as well.
So, back to your animals. To say what they are with more confidence, I'd like to talk to who sold them to you, as the description of "het albino and snow paradox" seem incredibly unlikely. Your two females that are "dbl het, albino/snow-paradox" are probably het for paradox albino and het for anery. Your male is very unlikely to be double het. You male is homogenous anery, and probably het paradox albino. It is possible that they are "albinos" not "paradox albino" traits, and that they are "het snow" not "het paradox snow."
Assuming they are all het for paradox albino, your outcome of breeding would have genotypes in the round abouts of: 12.5% paradox snow, 25% anery het paradox albino, 12.5% anery, 12.5% paradox albino het anery, 25% double het for paradox albino and anery, 12.5% het anery. The appearance of these animals will be 12.5% paradox snow, 37.5% anery, 12.5% paradox albino, 37.5% normal. There will also be no way of knowing for sure which animals are hets and which aren't, as there are no marker traits on the hets.
If this was all stuff you knew, sorry. To answer your direct question, if they're het albino het snow(aka het anery), you would produce snows, but if they're het paradox albino het paradox snow(again, het anery), you would produce paradox snows.
There are pictures up of the major KSB traits on the main forum,
