Honestly, I have never really heard of anyone breaking it down any further than "Lynx point".

All siamese tend to get darker as they age

I have (had) two lynx point babies myself. My late Sophie and my Espeon. Sophie looks more like your girl, whereas Espeon has a much darker body, closer to a typical siamese but with lynx points.

Oops, missed your question -- the babies look to either be lynx points like their mama or seal points (if there is no tabby stripes).

Please consider getting mama fixed!
