I added Ara Lilias to our 'to consider' list earlier today and I think I may have done it subconciously after seeing your signature.
These are lovely names that I think would make fantastic firsts or middles. A few of your names were a bit intense for me, but sound good just the same.
I want to like Calix but all I hear with it is 'cow licks'--like the tuft of hair that refuses to cooperate.
Lelia - I prefer this to Leila.
Like Calix, I want to like Decima it's too similar to the word 'decimate' for my liking.

Holden - It's only meh for me.

Scorpio - It's very soap opera-ish.
Tobias "Toby" - I like this one.
Wesley - It's a perfectly fine name. I prefer the nn Wes, though.
Draco - I like Drake well enough, but Draco still conjurs images of Tom Felton sneering at Daniel Radcliffe.
Edgar - Not my favorite "Ed" name. I don't care for the sound.
Galileo - Better as a middle, though Leo would make a fine nn.
Lysander - Eh.
Vale - Eh.
Atlas - I like it. I may be in the minority, but I think it's a usable name.

From your boys list I really like:

Holden - Love this one, it was on my list but my dh didn't like it
From your girls list I really like:
Luna - Love it!
