Some nice names on there.
I would spell Taliah as Thalia, Serren as Seren, Codey as Cody, Macie as Macy and Sydnie as Sydney. I would only use a top 50 name if I absolutely loved it, so that would rule some of those out for me, like Poppy, Freya and Erin.
Hadley is so due a comeback, love it! Classy and simple. Isadora, Tamara and Thea - classy too, as is Aurelia, though the 'rae' gives it a bit of a hard edge.
Honey - I like cutesy names but this is too cutesy even for me. What if she wants to be a barrister?
Carmen is fresh and cool.
NOT keen on Estee or Estera, they don't sound like proper names and the flick over the e in Estee would get left off a lot, meaning her name would technically being spelt wrong. What about Esther or Estella?
Isla is too of the moment for me, I reckon it'll be this decade's Tracy or Sharon (along with Amelie).
Boys names...all of your list is ok, apart from Zane - a bit harsh for a little boy. Flynn, Rafferty and Theo are the standout names for me. I would again rule out anything top 50 unless I loved it and spell Zac as Zack or Zach (or use Zachary and Zach as a NN).
