I love Lila and I like your boy names. I don't like Blair at all and I don't think it fits well at all with your other choices. Congrats on your twins!
Asher and Benjamin are great. Dislike Blair, and Lila is boring. What about Paige or Caroline?
I have negative associations with both. I'm a teacher, so names are hard. Also, we are naming after a family member who passed so it needs to be a B name.
Blair and Asher are Trendy McTrenderson. Lila is on the line in that regard. I don't love Benjamin, but it is definitely your best fn. Sloane is ghastly. Samuel is fine, Levi is great. On the whole, I would probably start over.
