Adrien Agreste/Relationships

Alya Césaire/Rena Rouge
Adrien seems to trust Alya's judgment; an example of this is when he suspected Chloé was Ladybug since Alya believed it. Though there is not much interaction between them, Adrien and Alya are friendly to one another when an encounter arises. Such as when they got pair together for a project with Nino in "The Evillustrator" and when they were talking to each other about Marinette's birthday in "Befana".

As Cat Noir, he also describes her as a "brave chick" to Ladybug when she is kidnapped by the titular character in "The Pharaoh". After Ladybug left he asked Alya if she wanted to know his age but by looking at his ring he ran away in fear. In "Dark Owl", Adrien comes to Alya as Cat Noir with Ladybug to ask her for a favor in helping the Owl live out his dream. She gladly accepts, and he praises her for her good acting performance.

Cat Noir meets Rena Rouge, Alya's alter ego, in "Sapotis", welcoming her to his and Ladybug's team with open arms. After she responds to his teasing with her own teasing, he notes that he has a feeling he'll like working with her. Cat Noir and Rena Rouge working well as a team, Cat Noir helps her by giving her advice when she needs it, and he is impressed by how fast she learns. When she leaves to de-transform, he bids her farewell by saying it was a pleasure to work with her.

They continue to be on friendly terms seen in "Syren", where the two help round up some runaway panthers and fight well together in "Mayura".

Lila Rossi
Adrien is friendly with Lila, but he is flustered and wary by her upfront passion towards him. While Adrien is upset when he learns the truth about her lies of being a superhero, he somewhat feels bad for her being harshly exposed by Ladybug. At first he believes Volpina is a real new hero, being supportive of her and suggesting that Ladybug should treat her nicely. Once he figures out Volpina is Lila, he tries to reason with her as his regular self, albeit awkwardly having to note that they weren't necessarily going on a date earlier before her akumatization. His response as Cat Noir to Lila's rejection of Ladybug's apology is "Ouch..."

In "Catalyst", Adrien is disappointed when Lila lies to the class about being in the kingdom of Achu and working on a pollution-reduction project, shaking his head in disapproval.

Kagami Tsurugi
Adrien treats Kagami respectfully as an opponent during their match in "Riposte", and he feels guilty for his uncertain win against her, a win that makes her depressed. Though he isn't initially aware that Kagami is a girl or that her family is famous in fencing, he treats her kindly, and he encourages her to try again at battling him in a rematch with a definitive winner.

In "Frozer", Adrien asks her about his romances on Ladybug she advises him to change to targets and the two spend some time at the ice rink together. When Adrien tells her he won't give up on his love for Ladybug, Kagami accepts his choice but says she'll be waiting when he quits.

Master Wang Fu
At first, he came across Wang Fu in "Ladybug & Cat Noir (Origins - Part 1)" helping him up. Adrien officially meets Wang in "Syren", where he was shocked as the man knew his identity as Cat Noir. When he comes to the mansion Plagg introduces Wang as the Guardian of the Miraculous.

Marinette's parents
Adrien first meets Marinette's parents in "Gamer" when he comes over to practice with Marinette for a video game tournament finding them nice and friendly and enjoyed watching Tom's cooking lessons in "Despair Bear".

As Cat Noir, he welcomed their help in protecting Kim in "Animan" as well as eyed their family photo smiling at their happiness.
