With the bolded section in mind: eliminate [name_f]Ava[/name_f] straight away. [name_u]Piper[/name_u]/[name_f]Audrey[/name_f] might have a second girl in her class possibly.
Not personally liking [name_u]Parker[/name_u] or [name_u]Logan[/name_u] as they sound gender bender style to me.
Of the ones left: #1- [name_u]Laney[/name_u] is very nice, [name_f]Ria[/name_f] is alright, [name_f]Estella[/name_f] is much frillier- but I doubt there will be many of them! [name_u]Hadley[/name_u] is lovely but increasingly popular, but I don’t think it’s crazy popular either.
[name_f]Audrey[/name_f] [name_f]Fleur[/name_f] in a heartbeat. I like [name_f]Estella[/name_f] but I don’t like [name_u]Kai[/name_u]. [name_f]Estella[/name_f] [name_f]Fleur[/name_f] is cute too, so is [name_f]Estella[/name_f] [name_u]Skye[/name_u].
[name_f]Estella[/name_f] [name_u]Kai[/name_u] is my favorite (although I would like it even better with [name_f]Fleur[/name_f] in the middle. It’s also not popular so you would get your unique factor. [name_f]Audrey[/name_f] [name_f]Fleur[/name_f] is great, and I don’t know any little Audreys, but statisically it’s kind of popular.
[name_m]Plenty[/name_m] of heads will turn for [name_u]Parker[/name_u] and [name_u]Logan[/name_u], they will just be little boy heads. [name_u]Piper[/name_u] is becoming very trendy.
[name_f]My[/name_f] vote is for [name_f]Estella[/name_f], then [name_f]Audrey[/name_f]. [name_u]Laney[/name_u] is very sweet, but I prefer it as a nn to [name_f]Elena[/name_f]/[name_f]Elaina[/name_f]/[name_f]Alaina[/name_f].
[name_f]Estella[/name_f] is my favorite. Not a huge fan of it with [name_u]Kai[/name_u], but it’s not a bad combo at all. [name_f]Estella[/name_f] is so pretty and underused. [name_f]Audrey[/name_f] [name_f]Fleur[/name_f] is my second favorite. 
I love the name [name_f]Ava[/name_f] … but it has become quite popular. I literally hear it everywhere.
Instead of [name_f]Estella[/name_f], I like [name_f]Estelle[/name_f] better! [name_f]Ria[/name_f] is nice, too. What about [name_f]Nia[/name_f] though? [name_f]Audrey[/name_f] is very pretty as well!
I love your list, we have a very similar style!
[name_u]Laney[/name_u] [name_f]Myah[/name_f] - I love the name [name_u]Laney[/name_u]! Though I would spell it [name_f]Lainey[/name_f]. [name_f]Myah[/name_f] is nice and they match well but again, I would spell it differently ([name_f]Miah[/name_f])
[name_f]Ria[/name_f] [name_f]Doe[/name_f] - not a fan of this one, [name_f]Doe[/name_f] doesn’t sound like a real name (at least I’ve never heard it before!) and [name_f]Ria[/name_f] is a bit simple for my taste. I think it looks better spelt [name_f]Rhea[/name_f].
[name_f]Ava[/name_f] [name_u]Neal[/name_u] - [name_f]Ava[/name_f] is a gorgeous name but popularity worries me. Never considered [name_u]Neal[/name_u] for a girl but works nicely as a mn.
[name_u]Piper[/name_u] [name_u]Skye[/name_u] - love this one! both names match very well
[name_u]Parker[/name_u] [name_u]Bleu[/name_u] - love [name_u]Parker[/name_u] for a girl, but not sure about [name_u]Bleu[/name_u] as a mn.
[name_f]Audrey[/name_f] [name_f]Fleur[/name_f] - like [name_f]Audrey[/name_f] but once knew a [name_f]Fleur[/name_f] who was awful so it’s forever put me off the name
[name_f]Estella[/name_f] [name_u]Kai[/name_u] - Not a huge fan of [name_f]Estella[/name_f] but love [name_u]Kai[/name_u].
[name_u]Hadley[/name_u] [name_u]Lex[/name_u] - [name_u]Love[/name_u] this one! [name_u]Hadley[/name_u] is gorgeous!
[name_u]Logan[/name_u] [name_u]Paris[/name_u] - nice, but having the two together sounds overly trendy.
Definitely [name_u]Laney[/name_u]! Always loved the name and would be so excited to meet one!
[name_f]My[/name_f] favorite was [name_u]Piper[/name_u] [name_u]Skye[/name_u] but I also like [name_f]Audrey[/name_f] [name_f]Fleur[/name_f].
I agree with above, [name_u]Paris[/name_u] is nice…[name_u]Laney[/name_u] would be my pick its unique, a lovely girls name and womans name. Good luck!
I like [name_f]Audrey[/name_f] [name_f]Fleur[/name_f] best.
