Stolas/Relationships

Octavia
Octavia is Stolas's daughter. Despite his feelings towards his wife shown in "Loo Loo Land", Stolas genuinely loves his daughter. He is seen comforting a young Octavia who is afraid that he will disappear and she won't be able to find him. After his affair with Blitzo, he takes her to Loo Loo Land in order to get out of the house and to spend some time bonding with her, while also using it as an excuse to spend time with Blitzo who he hired as a bodyguard.

Upon realizing his actions have made her once again afraid that he will run off and leave her, he drops the act of needing a bodyguard and leaves the park with her and takes her to some place which she wants to go to.

The ending of "Loo Loo Land" and a Voxtagram post shows that Stolas is somewhat uncomfortable with his daughter's liking of taxidermy, but supports her choices nonetheless.

Stella
Stella is Stolas's wife; in a flashback where a young Octavia had a nightmare, Stolas was a bit frustrated at Stella's coldness for not wanting to comfort Octavia. After his affair with Blitzo is made known, she scolds at him for cheating on her with Blitzo calling Stolas an embarrassment since Blitzo is an Imp. It is unclear of his feelings towards her, but there are implications their marriage was not one based on love, and possibly associated with status if Stella's words are to go by. Stolas admits to Octavia that he did try to make it work with Stella for Octavia's sake, but he just couldn't fool his heart anymore. Additionally, their relationship appears to be rather hostile, since she takes her responses to his infidelity to the extreme, up to the point of wanting him dead for cheating on her.

Stolas may not be fully aware that she is plotting to have him assassinated, if at all, as during dinner in "The Harvest Moon Festival", she demanded Striker kill him right in front of him while he was reading a book, only briefly raising his head to face her after he noticed her staring at him. It is possible that he did hear her but assumed she was talking about someone else, knows but just doesn’t care, or was simply not listening.

Blitzo
Stolas and Blitzo had a one-night stand. However, Blitzo only slept with him for a book that grants access to Earth and still hates him. Much to Blitzo's chagrin, Stolas hasn't forgotten the night and calls Blitzo for favors his business provides in a clingy, flirtatious manner. And yet, when Stolas wants Blitzo to get something done, he resorts to sexual and violent threats, which visibly disturb Blitzo to the point of destroying his cell phone.

It is shown in "Murder Family" that Blitzo had gotten a second (possibly burner) phone for Stolas to call rather than giving him his primary number. Blitzo makes no effort to retrieve this phone after the job implying that phone's only purpose is to keep Stolas from having his main number.

In "Loo Loo Land" he hires Blitzo and co as body guards and refers to Blitzo as his "knight in shining armor". At several points he feigns helplessness in order to have Blitzo save him despite him easily being able to handle imps. Blitzo appears willing to tolerate his flirting so long as him and his crew are paid and they keep it professional.

In "The Harvest Moon Festival", Blitzo and Stolas are shown to still be continuing their affair, with Stolas appearing to be trying out kink types with Blitzo. While the two engage in casual conversation, Stolas personally invites Blitzo and his employees to the Harvest Moon Festival in Wrath to apologize for taking his Grimoire back from I.M.P., but Blitzo ultimately didn't care afterwards about his clients and took Stolas up on his offer. Stolas was constantly referred to as Blitzo's boyfriend, which Blitzo always vehemently denied being and tried to state the more professional (albeit brutally honest) side of their sexual relationship. On stage, Stolas continued to flirt with Blitzo publicly despite the amount of people watching, much to Blitzo's chagrin. However, Blitzo seemed to care enough about Stolas to not want him dead (even though it seemed to be purely out of wanting to keep Stolas's Grimoire), having stopped Striker's attempted assassination of the Goetia Prince. However, Blitzo seemed to genuinely consider Striker's offer after he brought up how demons degrade Blitzo for being an imp, along with being reminded of Stolas's treatment of him as a "plaything", which appears to have hit a sore spot deeper than his need for Stolas's access to Earth. Stolas was completely unaware of all of this due to the failed assassination, and has no idea this transpired.

Loona
He has only interacted with Loona over the phone. Not much is known about what he thinks of her, however Loona does refer to him as a "clingy rich asshole".

Moxxie and Millie
Stolas doesn't appear to think much of Moxxie and Millie. In "Loo Loo Land", after the duo save him from an attempted mugging, Stolas is only concerned that it wasn't Blitzo who killed the mugger. He prefers Blitzo as his "knight and shining armor" and not Moxxie and Millie, whom Stolas calls "littler ones". Millie appears to ship him and Blitzo since she describes him as Blitzo’s boyfriend, although this may have been to annoy Blitzo.

Unnamed associates
While their number is unknown, Stolas mentions having several associates on Earth, which given the exceptionality of travel between the planes, might be human followers of some sort. Their endeavors are important enough for Stolas to contact Blitzo with the intention to order an assassination to eliminate one of their enemies to assist them.
