This one won't be as comprehensive; in fact, this'll just be me going off my own instincts, judging my own characters myself to see what House they'd be sorted into. Tell me if you disagree with anything~ 

Arianna Hayes: 

House: Gryffindor

Yeah, Ari's not the type to help out just anyone, and the girl can hold a grudge like a starving lion holds onto a zebra carcass, but deep down, she's a good person who'd do anything for friends and family. She's brave when she needs to be, and would never back down from a challenge. I think that lets her qualify as a Gryffindor, eh?

Violet Hayes: 

House: Gryffindor

Vi's nicer than Ari, hands down; she'd be the first of the sisters to offer help to a complete stranger (that may be naivety, but we'll call it kindness for now). She's brave in the face of adversity, as well, and the only time she's ever shown cowardice was when she had an angry Scar on her tail. So yeah, she's following in her (younger) sister's footsteps and proudly wearing her gold and red scarf.

Scarlette Hayes: 

House: Ravenclaw

I feel like this one's obvious. Scar the Brainiac would feel right at home in Ravenclaw, ya know?

Winter Heartfilia: 

House: Gryffindor

...Yeah. She's too much like Raya to be in any other House. Sue me.

Candor: 

House: Slytherin

I honestly cannot envision him in any other House. He's smart, yeah, but he's cunning as hell, has little to no morals, and doesn't have much consideration for human life. Not to say all Slytherins are like that, but he's so cutthroat and ambitious, I think it's just too fitting to have him in Slytherin.

Micah Viano: 

House: Hufflepuff

Micah likes to stand up for the little man, but she's not overly chivalrous, and she's not the type to just charge into a fight. I think Hufflepuff suits her.

Valentina Popova:

House: Hufflepuff

Oh, yeah, no, there's no question. She's a Hufflepuff through and through. Loves to help people, friendly with nearly everyone she comes across, hates violence... Yeah. No other House for Val.

McElroy Adriel: 

House: Ravenclaw

Okay, admittedly, I did the quiz for Adriel, because I seriously wasn't sure what the hell to do with him. And, surprisingly, he got into Ravenclaw. I suppose it's because he's open-minded, emotionally stable, and empathetic. Ah, wait, he kinda reminds me of Luna a bit, so this makes sense in a way...

Sainte Charlot: 

Designated House: Hufflepuff

Requested House: Slytherin

So you know how the Sorting Hat takes your choice into consideration? Well, Charlot would use that to his advantage so that he could stay with his brother instead of being sorted into the House he actually belongs in.

Sainte Charlemagne: 

House: Slytherin

The only person he cares about is Charlot, and he'd do anything to keep him safe and sound. That makes him ambitious in a not-so-nice way, and that's my reason for putting him in Slytherin.

Hansuke Holt: 

House: Hufflepuff

Just look at the guy. He's like Maddox. He practically screams Hufflepuff.

Esashi Kiyoshi: 

Designated House: Gryffindor

Requested House: Hufflepuff

Same thing with Char - he'd do anything to stay with Hansuke.

Esashi Katsumi: 

House: Slytherin

I'm putting him here because of how he acts in the current timeline of his story. But I'm also putting him here to show that not all Slytherins deserve their bad rap (which you'll understand if I ever get around to updating Cesspool...)

Hajime Naoko: 

House: Gryffindor

No question about it, this chick belongs with the supposed heroes of Hogwarts.

Catriona: 

House: Hufflepuff

Cat's brave and all, but if she could help it, she'd rather just have everyone get along.

Kitt: 

House: Gryffindor

Yeah...

Zeo: 

House: Ravenclaw

Zeo's intelligent, doesn't take idiots lightly, and is a bit of an introvert. I think he fits with Ravenclaw.

Tempo: 

House: Hufflepuff

Minus the emotional instability, and he's perfect for Hufflepuff.

Faline: 

House: Gryffindor

I don't really have an explanation for this one, I just think it's fitting.

Roronoa Naoise: 

House: Gryffindor

Same with Faline. It just fits to me.

Cadence: 

House: Hufflepuff

Because her only wish is to make people happy.

Falkov Galileo: 

House: Gryffindor

Unlike Maddox, Galileo has the skill and the presence to make it as a real marine, which is why I've settled him with the brave-and-true Gryffindors.

Falkov Gardenia: 

House: Ravenclaw

She's smart as a whip, and has an actual interest in pursuing knowledge (just not as openly as someone like Katana or Scar).

Silvestre Lakota: 

House: Gryffindor

He's a nice guy, but he's ambitious in his own right, though it's not for self-satisfaction like it might be for someone like Candor. He's brave to an extent, as well, so I think this is a good House for him

...I may or may not be putting together a book of sorts to have these guys actually attend Hogwarts. It wouldn't be a real story, per se, more like a collection of one-shots. Like UnchainedHeart's Crossing Blades, with Aoi and Kiyomi. So yeah. Would you guys be interested in that?
