Severus Snape does not have a sister in the official Harry Potter books; he was an only child, the son of Muggle Tobias Snape and pure-blood witch Eileen Prince. While fanfiction often creates sisters like "Evelyn Snape" or "Rose Snape," canon confirms he had no siblings, though he was distantly related to the pure-blood Prince family through his mother.
The marriage seemed to be unhappy, as they lived in near-destitution, frequently argued, and were neglectful of their son. With Severus's death in 1998, the Snape family may have become extinct, as Severus had no siblings and no children of his own.
But later, in The Deathly Hallows, it's revealed that the "awful boy" was actually Severus Snape, whom Petunia knew in childhood, long before Lily went to Hogwarts. Petunia and Snape never got along.

Voldemort found Nagini in Albania after his initial defeat, likely while he was a weak spirit possessing snakes; she was a unique, powerful snake, possibly a Maledictus (a witch with a blood curse turning her into a beast), making her an ideal companion, and he eventually made her his final Horcrux by murdering Bertha Jorkins with her present. Their connection deepened as he used her venom to sustain himself and later made her a container for his soul, ensuring their bond was profound and twisted.
Despite Snape killing Dumbledore, it is learned that they had a special agreement for him to do so. When he died, it was revealed that his deep strong love for Lily Evans caused him to redeem himself, joining Dumbledore's cause for her protection (and, after her death, that of her son) from Lord Voldemort.
Before boarding the Hogwarts Express, Albus confided to his father that he feared he might be Sorted into Slytherin. In response, his father told him that the bravest man he ever knew — Severus Snape, after whom Albus was named — had been a Slytherin student, making Slytherins not as bad as Albus believed.
Severus Snape's last words differ between the book and movie: in the book, they are a barely audible "Look at me," as he's dying from Nagini's bite, while in the movie, he says, "You have your mother's eyes," just before dying, a line added to emphasize his love for Lily Potter. Both versions convey his desire to see Lily's eyes one last time, but the movie makes it explicit, while the book leaves it more implied through his actions and the context of him seeing Harry's eyes.

Snape's tears, containing his memories, become the means for Harry to understand the professor's sacrifice, his love for Lily, and the necessity of facing Voldemort with the truth. While giving his tears was an impulsive act, it also symbolized his loyalty and dedication to Lily Potter's memory and Dumbledore's plan.
The main LGBTQ+ character confirmed by J.K. Rowling is Albus Dumbledore, revealed to be gay and to have had a passionate, intense love relationship with the dark wizard Gellert Grindelwald in their youth, though this isn't explicitly detailed in the books but rather in later interviews and supplementary materials.

Page 394 in Harry Potter and the Prisoner of Azkaban refers to Professor Snape telling the class to turn to that page in their Defense Against the Dark Arts (DADA) textbook, which is about werewolves, a deliberate hint that the substitute teacher, Professor Lupin, is one himself, a secret Snape was trying to expose. While the specific text varies slightly by edition, it introduces the topic of werewolves as nocturnal beasts, contrasting with the Red Caps and Hinky-Punks they were learning about, to reveal Lupin's true nature.

Snape hated Gryffindor's guts and valued ambition. Thus, Slytherin. Besides you can be one house and still have traits of the other. If you put it this way, Snape is more Hufflepuff than gryffindor, as his bravery induced from his immense loyalty towards lily.
