In this post, you'll find something along the lines of what Ryuunosuke thinks of the Housemates he's interacted with, as well as some info on his relationships with important people back in his home world who aren't here, just in case things get confusing or people are curious as to who he's talking about (as he does make references to things back home).
If I've left someone out from Taedium, or you'd like me to add something to what I already have, feel free to leave a comment!

Acquaintance
As of right now, they're just casual aquaintences. Even though they haven't talked too much, Ryuunosuke has started to develop a platonic fondness for her.

Acquaintance...?
Ryuunosuke helped save him from zombies a while back, due to his mentality of protecting citizens and just helping people. They've never talked.

Acquaintance
She helped Takeru and Ryuunosuke with Takami back when there was a zombie invasion in the house, though the two of them haven't had much, if any, interaction since.

From his own world:

RELATIONSHIP:
THOUGHTS:
firesamuraiShiba Takeru
Lord, boyfriend, teammate
Ryuunosuke is willing to sacrifice his own life for the young lord, having almost died once while protecting him. He will do anything for Takeru, no matter what it is, though they do occasionally argue. As of a few weeks after first arriving in the House, their relationship had gone from platonic to romantic, and Ryuunosuke and Takeru are now boyfriends.

Friends, teammates
In the small interactions the two have, they get along well. Because of their friendship, Ryuunosuke will help her out if she needs it.
Tani Chiaki - ShinkenGreen, and Ryuunosuke's teammate and fellow vassal. The two tend to fight a lot.
Shiraishi Mako - ShinkenPink, and Ryuunosuke's teammate and fellow vassal. The rest of the Shinkengers see her as a sister, as she's always taking care of them. However, her cooking is terrible. It's possible that Ryuunosuke might have had a small crush on her at one point, though those feelings are gone now.
Umemori Genta - ShinkenGold. Ryuunosuke is only just starting to accept him as a teammate. Because Genta is an old friend of Takeru's, and has gotten a little too physical with the young lord for Ryuunosuke's liking, he sees him as his greatest rival for Takeru's affection, even though he really doesn't have anything to worry about.
Kusakabe Hikoma (a.k.a. Jii) - He raised Takeru after the death of the young lord's parents, and has become the mentor of the Shinkengers. As the unofficial 2nd-in-command of the team, Ryuunosuke will sometimes report to Jii in Takeru's place.
Komatsu Sakutarou - A kuroko who served the Shiba household until after the death of Takeru's father. When he first crosses paths with Ryuunosuke, he is a fisherman. Ryuunosuke manages to open his eyes to serving a lord not just because you have to, but because you want to, by continuing his efforts to catch the Kajiki Origami in order to save his teammates (specifically Takeru) from a deadly poison that can only be cured with its power, even though he could barely stand. After helping Ryuunosuke capture the Kajiki Origami and the samurai returns to the city to help the others, Sakutarou returns to the Shiba estate and resumes his duties as a kuroko. He and Ryuunosuke haven't talked to each other since that day.
Richard Brown - An American who wants to learn the way of the samurai, and is an obsessive fan of the Shinkengers, particularly Ryuunosuke. The others do their best to drive the foreigner away, but Ryuunosuke takes pity on him and officially takes him on as a student, though when Ryuunosuke gets frustrated and tells Mr. Brown that he can no longer teach him, he misinterprets the words as having completed his training, and interferes with the Shinkenger's battle a second time. However, right when the Shinkengers seem to have given up hope of defeating this particular Gedoushu, he reminds them that samurai don't ever give up.
Juzou - A man who is half human and half Gedoushu. As a stray, he freely wanders between the human world and the Sanzu River, helping whichever side he feels like. He has an obsession with testing Takeru's skill, though the two haven't clashed much yet. Of the few times he's shown himself to the Shinkengers (and as of the end of episode 19), Ryuunosuke has only ever seen him once. It is still hard to tell which side he's really on. As of recent canon, Takeru killed Juzou in a fight to the death.
