At birth, albino white, ermine, Californian and fawn (orange, depending on breed) kits look similar. They start out all pink. After a few days, the hair will start to emerge. Albino white, ermine & Californian (aka Himalayan or pointed white) will start out all white. Once the eyes open at around ten days, the points on the ermines & Cals should also start to come in. REW & Cal will have red/pink eyes, ermines often have the chinchilla grayish eye.
The kits with non-extension ee will start showing the yellow shades in a few days: cream/fawn/orange/red. Agouti non-extension will be fawn/orange and show that lovely golden hair all over. The dilute (called fawn or cream depending on breed) version will be paler, more of a beige shade. Those with high rufus will look redder. Non-agouti (self) non-extension aa ee is called tortoiseshell, 'tort' for short. Here, you will see the same yellow tones on the main body, but the points (nose, ears, feet and tail) will have one of the four dark colors, which are black or chocolate, and their dilutes blue or lilac.
It looks to me like the top mystery kit has shading around the head and ears, and on the lower body, which makes me think tort.
