Gabriella - love it but not sure it goes with Lyra and Renn and really don't like Gabbi
Crescent - is this really a name? I don't like the sound anyway.
Eleanor - like it but not keen on Ellie or Nell
Winter - like it. Think it goes well with Lyra and Renn
Emily - sweet but way too popular to go with Lyra and Renn
Erin - really like it. Is the sound too similar to Renn?
Elsa - it is actually a pretty name. And it would be cute if your daughters had named her. It goes too.
Bear - not sure about this at all, I think it's a bit odd
Torak - actually really like this. And it goes with Lyra and Renn
Hawk - no, way too far for me.
Eric - no, middle aged man
From your lists I'd choose Winter or Elsa and Torak. Other ideas:
