Name for my little brother

Hello!!

[name_f]My[/name_f] mom is pregnant with my little brother who will be born in the begining of [name_f]July[/name_f]. Im really excited about getting a new brother, but we seem to be not able to settle on a name. [name_f]My[/name_f] name is [name_f]Leah[/name_f], my sisters name is [name_u]Asa[/name_u] (pronounced ah-sa) and my brothers name is Ryuki. (pronounced Dyu-kee). Our names sound weird because we live in Japan and our dad is Japanese. Anyway, weve been thinking about names, and this is what we`ve got.

[name_m]Louie[/name_m]
[name_u]Noah[/name_u]
[name_m]Samu[/name_m] (Kind of like [name_u]Sam[/name_u] but Japanese sounding.)
[name_u]Kai[/name_u]
[name_m]Aaron[/name_m]
Tysei

Which name do you like the best? Also, I would love new suggestions:)
Middle name will be [name_m]Richard[/name_m] to honor my uncle who died recently.

Thanks!!1

[name_f]My[/name_f] suggestions

[name_m]Samuel[/name_m] [name_m]Richard[/name_m] nn [name_m]Samu[/name_m], [name_f]Leah[/name_f], [name_u]Asa[/name_u] and Ryuki sounds like [name_m]Duke[/name_m]?
[name_u]Elliott[/name_u] [name_m]Richard[/name_m] nn [name_m]Eli[/name_m]
[name_m]Joel[/name_m] [name_m]Richard[/name_m] because it goes with [name_f]Leah[/name_f]
[name_m]Malachi[/name_m] nn [name_u]Kai[/name_u] is a possibility but not so fond of [name_m]Malachi[/name_m] on its own or [name_u]Kai[/name_u] on its own
[name_m]Kian[/name_m] [name_m]Richard[/name_m] nn [name_u]Kai[/name_u]
[name_m]Aaron[/name_m] [name_m]Richard[/name_m] is nice but not sure if you want siblings sharing the same letter ie “A”.

Thanks, rollo for your suggestions:)

I know Ryuki sounds like [name_m]Duke[/name_m], but my mom didnt notice that until he was about three and my uncle pointed it out. Haha. Ryukis name is to honor my dad`s bestfriend, [name_m]Ryu[/name_m]. We pretty much call Ryuki, [name_m]Luke[/name_m] when we go to [name_u]America[/name_u] and visit family.
