So Murray's thoughts on Jamil dating Floyd would be neutral at first as expected. Like oh cool my son's dating someone and they seem decent, good for him. She basically already accepted Jamil into the family. Though Murray's head would perk up after hearing Jamil knows how to cook, Murray comes from a foodie family (and was the one who taught Floyd and Jade how to cook) so hearing her son got with someone who's not only a decent person but ALSO KNOWS HOW TO COOK?? YAHOO!! It'd give Murray a chance to learn what Jamil knows about cooking and what dishes he can cook, while in return she'd teach some tricks and possibly how to cook new meals to Jamil as well. This is probably the best outcome for Jamil, even though he doesn't enjoy cooking as much as Murray (unless he's cooking for Floyd), it's the easiest way to get along with what could possibly be his future mother-in-law and get on her good side without an issue. (For Jade I'll use both Azul and Vil as examples)

If Jade ends up dating Azul, Murray wouldn't be surprised really since they did grow up as childhood friends, and seeing them close to the point of dating would be no surprise for her. She already liked Azul and thinks he's a funny kid. And he was already considered a part of the family, now that he's straight up dating one of the tweels he's basically given a spare key to their house and can now enter and be welcomed into it whenever he feels like.

If Jade ends up dating Vil, Murray would probably be the only person to not give a single flying fuck that Vil is a famous model/actor, Vil is just another person to Murray and ofc she has a neutral stance on them at first. Vil would not have an issue with Murray accepting them as Jade's partner, but I think a small problem that'd cause trouble at first is when Murray finds out about Rook. In the Coral Sea, it is very not uncommon for a merfolk to be stalked by something and that usually means danger. So finding out about Rook would cause Murray's alarms to go off thinking her son could be in danger, and Vil would probably have to force Rook to come introduce himself and show her he's no danger at all, because if he doesn't that might risk Vil and Jade to break up. But after finding out Rook is no trouble Murray would go back to her normal "Oh okay cool" state and just accept Vil into the family with no issues anymore. So like, funny enough Vil might be only one who struggled with being accepted by Murray JUST because of Rook and I think that's funny as fuck.

Now with Sirena, unlike Murray who's full on "okay cool" with any person that her sons end up dating. Sirena would like to first get to know the person before she decides if she likes them or not and if they're a good fit for her son. Sirena is probably the parent you'd have to work at least a little bit harder to get her approval but in the end she will be the most supportive if it works out.

Her thoughts on Jamil dating Floyd, first thing she'd think after seeing Jamil is aw he's very pretty how cute. Though after talking for a while and witnessing how Jamil is with Floyd, she'd quickly take a liking to him after noticing how loving and patient Jamil is with Floyd, kind of like how Sirena is with Murray. Made her start seeing a bit of herself in Jamil after noticing their similarities. Sirena's biggest worry was if the person Floyd was dating is able to handle his mood swings. Since Sirena knows how to handle both Murray and Floyd's mood swings (meaning, a LOT of patience) she was worried the person who Floyd ended up with might not be able to and therefore would end up breaking his heart because of it. But hearing how Jamil is one of the few people who knows how to deal with them, she felt instant relieve and the weight on her shoulders vanished completely. After they get along, Sirena constantly tells Jamil if he needs any help with Floyd, she's there to help and might even tell him about the silly things Floyd has done when he was a child while she does so (usually Murray is the parent that embarrasses her sons but sometimes Sirena has to do it as well)

Now with Jade

If Jade ends up dating Azul, Sirena would be OVERRR THE MOON SUPPORTIVE WITHOUT HESITATION. I've mentioned before how Sirena and Azul's mother used to be high school besties when they were younger (and they are kinda the reason why the tweels and Azul started hanging out after they reconnected). So hearing that her son is dating her bestie's son has made her overjoyed completely, not only do their kids get along, but they're also dating? How cute! I do not doubt Sirena and Azul's mother gossiped about it for a good while they're happy to say the least.

Now if Jade ends up dating Vil, I think Sirena would have the most normal reaction to suddenly finding out your son is dating a famous model/actor "Huh what the fuck". Think she had to process it a little, she was aware of who Vil was already (since, who wouldn't be) but finding out her son was dating them was a whiplash she wasn't prepared for at all. After the shock factor, Sirena would take a moment to get to know Vil just like how she did with Jamil, and learn okay yeah Vil does seem to love her son and treat him well and she's happy with that, but it might take her some time to get used to and have the shock turn down from finding out now a famous model is part of your family. Sirena also got a bit spooked by Rook (not as much as Murray though) but calmed down pretty quickly after Rook casually waved at her and she waved back after she noticed him, of course calming down more after Vil introduced Rook to them, she finds him strange but not a danger so I guess that's another thing she will have to get used to lmao
