The coat pattern and coloring associated with the Californian breed is common in many others breeds too. The top rabbit has a fairly distinctive Holland Lop look. I don't think the coloring is due to mixed breeding in this case.
I would say top one is a pointed white Holland lop (I would not say its has cali in it) and the bottom one is a broken chestnut holland lop or mini lop not sure, it could just be a non-dwarf holland lop.
