I think No#3 is the best sibling set. They're all well matched in style.
The two boy sibsets No# 7 and No# 8 are fine too.
My preference is for children to have their own initials so No# 9 and No# 10 are not ideal. I also like each child to have different name endings so No#1,2,4,5 and 6 need some tweaking as well.
