3. Ask them to describe their love interest.
He doesn't currently have one. Not in the present at least.
6. Who will they take advice from, no matter what it is? Who won’t they take advice from, no matter what it is.
He'll take advice from quite a few people. Advice will be strongly considered from his sister Oprena, from the Elders of his extended Family, from his little cousin Pipa, from Dr. Bilkardy,... Most people he's close to, including his... Islandmate ? Ganara. Also, and probably the most improbable to happen, but if one of the nature spirits he's devoted to were to advise him directly, he probably wouldn't turn that away.
As far as not taking advice, he won't listen to anything Lady Seric has to say, of course. He's very reluctant to listen to anything a Vhigg'ithu (the Merfolks of his home plane) has to say. He generally ignores his "friend" Shaw because he thinks Shaw has a very different view of the world than he does.
13. Name one thing their parents taught them.
Another one without biological parents... But his Elders taught him, with a lot of care, how to craft a heat pendant out of lifewood should his own be lost or damaged, and to always keep a spare piece of lifewood with him for that purpose. He, like other Ghavaleks, is cold-blooded, and outside of the volcanic waters their native villages are built around, he needs one of those to function properly for more than a few hours and avoid losing all of his body heat.
15. What would they consider a waste of time– other than school or work?
Administrative formalities. It doesn't help that until very recently, he didn't know how to read or write and that he's still currently learning how all of that works. He comes from a way of living without any of that, and it seems unnecessarily tedious, boring and pointless.
18. Kissing: tongue or no tongue?
No tongue. Biologically, his tongue doesn't leave his jaws and most people he's with don't reach very far there even when they try to find a way to kiss him.
20. What do they like that nobody else does?
Not everyone, but there's very few people in the Multiverse that like sunbathing quite as much as he does. Even other Ghavaleks don't get the full experience, since Ocaelum has no sun. The closest they get is Lifetrees, and as Arnoss noticed, it's not exactly the same.
29. What recurring dreams do they have?
Arnoss doesn't remember many of his dreams, but he does sometimes dream of the monster everyone sees him as, and the monster he thinks he'll become.
