Your adult rabbits could carry the 'cali' markings, which is actually called the himalayan gene, but it would not be making their ears and nose dark, that is all done by the broken gene. Think of a Californian or himalayan marked rabbit as a pointed red eye white, they will have no colour anywhere except on the points and will have red eyes.
I think Natalie is an agouti, sometimes called a chestnut. And agree that Mike is a broken harlequin also known as tri-colored
The dark kits look like they will be chestnuts rather than harlequin.
The kit with colored ears, nose and a few spots will also likely be broken chestnut like mom
The completely white kits could be REW, if their eyes turn out to be red. If they have a dark eye then they are 'charlies' as MamaSheepdog mentioned and have two copies of the broken gene, any white kits that have even a tiny spot of colour will also be 'charlies'
