The two on the right are Hikaru and Lala from last year's installment of the long-running Pretty Cure franchise, Star Twinkle Precure, while the left is Nodoka from this year's installment, Healin' Good Precure. Lala happens to be the first alien girl to become a Precure (Star Twinkle was a very weird installment) and she has cute little antennas that she uses for various things, including greetings and showing affection/friendship.

i gotta admit i don't actually know the characters lol
Then go watch Revue Starlight. It's an excellent show with great action and an interesting story, plus plenty of yuri undertones and interesting pairings among the girls. It's one of my top 5 favorite anime of all time. ---
