Make an alt account if needed to spawn more and friend that alt account to have them send help request to your main.
Your fire team is extremely lacking in debuffs. You literally don't have a single one with that set up unless you use a ex skill on Andromeda. Since you say you have Gaia, even a wind team would be better with Cybele (story) and Zephyrus (from gem gacha).
I hope you have some other souls unlocked too since Andromeda is unnecessary in your water team, with Aphrodite and Nike more than enough to handle the heals, you could have gone for someone else.
