I would say pretty easy:
Artemis>>>>>>>>> Zelda>> the rest.
I would say, for me, fighting for a first place will be Paige and V (difficult choice). For a second place - Kindra and June (also difficult choice), third place - Zelda - after them, rest of the girls
Paige - she is just so... difficult to explain it... warm and friendly, but in non pushing way, not trying to force you to anything. Sometimes with a bit too much over her head, but also 'positively twisted', a little crazy sometimes, but in good, non harmful way.
V - she is just a curious one. It seems, that she has some secret from the past (she mentions to hersolf to not egt involved into sth again, so I wonder, what did she in the past to give such warnings to herself). Also - quirky, but in a way, that shouldn't be harmful. But, above all, she is a bit nerdy, for sure intelligent and has great knowledge (she created her own debugger). I salute her.
June - a bit similar to Paige, but much more dynamic, expressive. Smart and knowing what want to do. But, most of all, she had bad moments in life and did not allow them to destroy her. She managed not only to get up and start anew, but also, help others do so - Aiden. Deep respect to her for that.
Kindra - I like a lot her relation with Aiden, their time in school, and later. Similar to June, she had a lot on her shoulders, but of different kind. Still, she is struggling, but has help of friends. She also has heart of gold, is very loyal to people she trusts.
Zelda - residential vampire

I really like her calm and serious personality. The way, she approaches the world.
