I'm gonna say 3 for Leon, Luca, and Trinity, but in particular, in an out-of-universe sense! What were you thinking when you named them, what was the process and were there potential fun alternatives?
Leon's name is of course the oldest, since his goes back to the old Cat Comixz days. Originally, Leon and Melody were names I was going to use for kids if I ever had them, though they ended up bestowed upon my delightful cat children instead.
Unfortunately since those were names I picked out back when I was in late middle school, I can't say for certain where they were originally inspired from. Best guess with Leon is his namesake being Leon from Kingdom Hearts. Not even the Final Fantasy game he's from, no, from Kingdom Hecking Hearts.

I truly wish I had an interesting and deep line of reasoning behind Luca's name, but really the best I can offer is that when I was first coming up with the character, that name just immediately jumped into the forefront of my mind. It was just "okay here's this character concept LUCA HER NAME IS LUCA IS CANNOT BE ANYTHING ELSE." I probably owe Square Enix again for this one, since I'm pretty sure I first heard Luca as a name in Final Fantasy X... though in that game, it's the name of a city.

Trinity's name is actually a relic from the Pre-Alpha version of KttFF. Basically, before I actually had any real concept for the story beyond "Leon ends up in the far future," the comic was going to be stuffed to the gills with references to sci-fi media. Probably not like clever or meaningful ones, just references for references sake.
I had to get down the genders of the Future Siblings first, but that took a weirdly long time; I was pretty confident about Ms Shepard (named after Commander Shepard from Mass Effect), but I was having trouble with the other sibling. (I'd like to pretend Trinity being trans was a Clever Nod I specifically planned out before the comic started, but that honestly just developed naturally along with her autism.)
Anyway the point is I eventually settled on The Other Sibling being a woman, and basically went down my list of Arbitrary References to make and figured, "Eh, Trinity (from the Matrix) is as good a name as any."
Again, I didn't plan for Trinity to be trans as KttFF was starting. So that fact that her name is on loan from a film where the directors both came out as transwomen after the fact? That's personally one of my favorite aspects of Trinity.
