Joy started off living in poverty, but she went to live with and married Ragnarok, who had a rich family before but has earned his own wealth due to being a highly ranked assassin for a large mafia-like organization. They lived in their fancy schmanzy beachside estate and due to their ownership of the largest trade cartel on their planet, they basically own most of their region. All their kids were born into this wealth too, although not all of them still live in the high rolling life all the time now that they're grown up.
Lancer and Marquis have taken over the family business with the cartel following their father's death, so they're rich CEOs/executives. Cyan is well off on her own since she's a well-performing surgeon. Argent is a Lieutenant Commander in their world's Navy, so he earns quite a bit too. Cornell is a pirate captain and ends up taking a lot of loot, although since his family is already rich and he can just ask mama for anything in an emergency, he tends to donate his excess treasures/wealth to their community. Shrike doesn't bother with any of that and just lives a solitary life on an island with his birds, but he visits home regularly and can get anything he needs from mama as well if necessary. Turul and Tilia live a pretty simple life, although they earn quite a bit of winnings from their success in an underground fight ring. And Freyr and Shakuru live at home still to help mama take care of their large estate, although Shakuru also has a job as a marine biologist and could probably provide for himself if he wanted to. The only one who hasn't grown up in this wealth is Fathom, since he ran away from home as a child. ^^; After making amends with his family though, mama insists he can ask for monetary help whenever he needs it though, but he's hesitant to mooch off them after all this time away.
