Can someone ID these bristlenose plecos for me?

[saganco]

These are all "bristlenose" of some kind, but folks on other forums have me second guessing myself. So I won't even mention what I think - just would appreciate you guys’ expert opinions.

The adults (#1-4) were bred and sold to me by an older gentleman who was the first in the US to bring plecos into the US. I wouldn’t think that he would sell them as calico’s if they aren’t – he is an expert after all…

So what would you say about these little ones? Calicos? Hybrids? They are an orangish color, but have lots of polka dots… Dad was one of the ones above (#1-4), but mom was either an albino or another calico. I just want to get the adults and babies named correctly before I go about selling them.
