Names for a story I'm writing?

In the story that I'm writing, the family has 3 year old triplets(which is 3) and 10 month old septuplets(which is 7) do you like the names I chose? For the triplets there are 2 girls and a boy. Sadie Gabriella, Grant Alexander and Stella Madison. And for the septuplets there are 4 girls and 3 boys. The girls names are Kaleigh Elizabeth, Kyleigh Marie, Noah Jacob, Nolan Andrew, Kailyn Sophia, Kaitlyn Paige and Nathan Troy. Please tell me if you like these names or not. If you don't like one particular name, let me know of a name that you do like. (the girls' names must start with a K and the boys' names must start with an N.)
