@Rozalka cinnamon blue?? are you sure? coz as per my knowledge, to be a cinnamon it needs to have a light brown feathers and markings instead of black. I think its an Opaline as its mother is an Albino and father is a yellowface blue opaline.
Also the 3rd one is dominant pied or recessive?
No, I wasn't sure

I also was thinking about the opaline mutation but I'm not sure because the "wave-break" is so small. I've just found on the Internet a good comparision of opaline and "non-opaline" backs:
They are green, but in blue it works simillar. As you see this changes the shapes of waves but not the color. It means that there have to be one more mutation something like cinnamon (yep, the waves shoud be brown) or dilute (there are 3 types of this mutation)
About the type of pied I can't help
