River 7/10 (if you've got a surname that really works with it)
Seren 3/10

Asher - 5/10. I don't dislike it but I have met quite a few girls called Asha so it seems quite feminine to me. I really like Ash for a nn though.
Caspar - 7/10. Prefer the Casper spelling.
Caspian - 8/10. My favourite of your list
Idris - 6/10. I do really like this but I think everyone will assume you've named him after Elba.
Judah - 4/10. Prefer Jude but I'm not a huge fan of biblical names

Arietta - 5/10. Too flowery for me. I do like Arietty though
Aurelia - 5/10. Don't really like the sound of it.
Eadlin/Eadlyn - 4/10. never heard this before. Is it like eed-lin? I'm not keen
River - 0/10. Just really dislike this.
Seren - 7/10. Pretty

another vote for Caspian and Seren. Do like Aurelia also. Judah just brings to mind Judas, just feels a bit negative.
