What is considered an “acceptable” or “good” greek name?

Im writing a story right now that follows a greek girl and her journey to find her long lost twin brother. I was wondering if any of the names I’ve used for her family may be a bit too steretypical or used in bad faith?

Here are the names by the way!

Alexis Drako

Nikolaos Drako

Nefeli Drako

Cassandra Drako

Georgios Drako
