Well, I’ve done a bit of this answer? Definitely Thorin’s and Frerin’s reactions to their namesakes, anyway.
Thorin’s response to the naming of Dwalin’s last child was utter gratitude. He immediately dragged his brother close and held him as Frerin reeled with the knowledge that he was not forgotten.
(Then Thorin had to endure three straight days of Frerin crowing about it.)
Dis’ reactions to all three, though…
Dis’ reaction to Wee Thorin’s name was to stare at Dwalin as though skewering him through with daggers made entirely of her will. Then she said, “another one.”
Dwalin had the good grace to look sheepish.
When Balinith came along, Dis only clenched her jaw and sighed.
When Frerinith came along, and Dwalin told her the name Orla had chosen (hesitantly, his massive hands wringing the edge of his tunic), Dis had to stand and leave the room very quickly.
She’d nearly forgotten what it was to cry with happiness.
