They are both "pointed cats." The first is a "blue cream tortie point." Or a "diluted tortie point." Same thing, different names. Genetically, she's a tortoiseshell, a black and orange cat (black and orange genes are on the X chromosomes; she has two X chromosomes as a female, one black, one orange, both are expressed). The black and orange is "diluted" by another gene which turns the black into the blueish grey and the orange into cream. The pointed gene restricts the color to the points. So a blue cream tortie point
The second is a blue point cat (I think some people call it lilac point). It's a genetically black cat (either X(black)X(black) if it's female or X(black)Y if it's male). Like the tortie point, it carries the dilution gene which turns the black into "blue." And also, the pointed gene which restricts colors to the points.
A seal point is a black cat with no dilutions and the pointed gene, so it would look like your blue point only with black instead of blue. The "pointed gene" is called the himalayan gene, and it's actually a form of albinism. It restricts pigment based on temperature. The body parts that stay hot stay white. The body parts that get cooler (face, ears, tail, legs) will show pigment. All pointed cats are born white since they've been toasty in their mamma. They get darker as they get older (both of these cats will most likely get darker), and many pointed cats are darker in the winter than in the summer.
In short, Kitty #1 = Blue Cream Tortie Point (or Diluted Tortie Point).
Kitty #2 = Blue Point (or Lilac Point).
