Naomi Katherine is really pretty. I haven't heard the name Adalae before, but I LOVE Elizabeth.
Jackson Levi is fine, though it's personally not my style. I think you may change your mind as you begin to do more research on baby names, and you see how popular Jackson has become. The popularity might bother you.
I have only heard the name Adalae in the song. But it's just so pretty!
I think looking into the popularity of names in the US would be a good idea for me. I'm originally from Canada and have only been here for two years now. It's been interesting to see the different baby name trends in the two countries. I didn't know anyone with the name Jackson before, and the one I do know is American. The popularity of Jackson might bother me... bummer. 
I'm not sure any of these names are good choices if you are concerned about popularity, with the exception of Naomi and Levi. Adalae may seem cute and unique, but it sounds just like Adeline, Adelaide, and Addison along with all the other "Addies" that are VERY, VERY popular. I see a little Addy/ Addie every time I go out in public. I've loved the name Addie since I was a kid but won't use any of these variations (except possibly Adele, my great-grandmother's name - still stuck on it!) due to the popularity. Adelae is very similar.
Agree that Jackson is insanely popular in the US. Check out the SSA name lists, and you can also see which names are rising fastest in popularity.
