Nazuna After hitting, you have to use precise timing, and at a steady pace enter the commands. Back, down, back, down, back, down, back, down, back+AB.
Akane After hitting, you need to RAPIDLY mash buttons. Getting full damage is incredibly difficult.
Elsa It's a two part move. Use her down, up+attack command. When the bullet is at it's highest point, enter the Critical Heart command.
Saki After the first hit, enter down+A, down+B, B, C, E, down+E, D, B, C, up+C, down+C, E. Just hit the next button when the previous attack is hitting. There's a slight pause after the hit that launches you into the air.
Kamui Use her standing counter attack (DP+B) and when the enemy hits, before she does the counter, enter the Critical Heart command. I don't remember if you need to be powered up with her down, down+attack or not.
