For the girls, I would veto/delete:
[name_u]Zeppelin[/name_u] (literally a [name_m]German[/name_m] rigid airship. [name_f]Non[/name_f] traditional word names can be cool but this is really too military… which is not something I would like. Yeah.)
Kabria (Sounds too modern IMO and likely to get misspelled. The other names are names with important meaning or backstories.)
I would eliminate simply because it is NMS, though they are perfectly fine names so use them, but on case you need to clean the lists here are some ideas:
[name_f]Ophelia[/name_f] (in the US, rising, and feels “trendy” for me. I would use [name_f]Ofelia[/name_f].)
[name_u]Willow[/name_u]
[name_u]Avery[/name_u]
[name_u]Jean[/name_u]
[name_f]Emmaline[/name_f]
[name_f]Charlotte[/name_f] Cordelia-DeAnn
[name_f]Jillian[/name_f]
“These names are okay”:
[name_u]Evelyn[/name_u]
[name_f]Eleanor[/name_f]
[name_f]Violet[/name_f] Melissa-Ivorie
[name_f]Penelope[/name_f]
[name_f]Isabella[/name_f] (I would usually have put it in “I love” but compared to the other gorgeous names this is a little too bland, and in the US it is popular unlike in my country! And since you are naming an actual child…)
[name_f]My[/name_f] absolute favourite from your lists:
[name_f]Tallulah[/name_f] Hazel-Blume 
99/10 This one is so Telegraph-ly surprisingly modern (in a good way!) yet somehow eccentric and spunky (in a even better way!) while being romantically cool. It is also so bohémien and [name_f]Blume[/name_f] is a great [name_m]German[/name_m] word name (Blume was used generically in the past, [name_f]Bluma[/name_f] was a common yiddish name) and sounds a little vintage yet poetic for me. It sounds like a song written for children that is timeless or a ballad of the medieval times, but with modern feels in it. It sounds like nature and green for me, and has so great meanings. I never thought of this but this is so fantastic. So Telegraph-ly beautiful. Very different from other names of your lists but I would use this!!!
[name_u]Camille[/name_u]
[name_f]Adeline[/name_f]
[name_f]Iris[/name_f]
[name_f]Iris[/name_f] means rainbow and symbolises peace and prosperity. It is also a great namesake for this month
It was a name from the Greek mythology. And to me it can be classic, modern or vintage. It is simple to use in all the world
[name_u]Marlow[/name_u]
[name_f]Calliope[/name_f]
[name_f]Calliope[/name_f]! It means beautiful voice and was the name of one of the most important muses. I bet your girl will love the namesake, and you also get the whole Iliad starting with her name - “Sing to me, oh my divine Calliope…” It starts like this!
