Scooby-Doo has one sister, Ruby-Doo, who is also the mother of Scrappy-Doo, and he has several brothers (Howdy-Doo, Skippy-Doo, Yabba-Doo), but Ruby-Doo is his only named sister featured in the franchise.
Scooby has three brothers; Howdy-Doo, Skippy-Doo and Yabba-Doo, and one sister, Ruby-Doo (who is Scrappy's mother). Yabba-Doo is a little dubious since he and Scooby never actually interact, but since Scrappy calls him "uncle Yabba," it's generally accepted that he's probably Ruby's (and therefore Scooby's) brother.
Ruby-Doo is the mother of Scrappy-Doo, the only daughter of Mumsy and Dada-Doo, and the younger sister of Scooby-Doo.
Daisy, Dawn, Delilah, and Dorothy Blake: Daphne's sisters, that are identical, from Scooby-Doo! Mystery Incorporated.
The main LGBTQ+ character in Scooby-Doo is Velma Dinkley, who was confirmed as a lesbian in the 2022 film Trick or Treat, Scooby-Doo!, showing a crush on costume designer Coco Diablo; this solidified long-held fan theories and creative intentions from writers of shows like Scooby-Doo! Mystery Incorporated who had tried to portray her as gay for years. Other characters, like Coco Diablo and even Marcie Fleach (Velma's friend in Mystery Incorporated), are also identified as queer or lesbian within specific contexts, but Velma is the most prominent.
After Daphne and Velma were friends as children until Velma became too absorbed in grief over her mother's disappearance to focus on their friendship, which resulted in Daphne finding new friends. Velma has a panic attack and Daphne kisses her to calm her down.
Shaggy Rogers from Scooby-Doo has had several girlfriends, with notable ones including Googie (from Scooby-Doo and the Reluctant Werewolf) and Crystal (from Scooby-Doo and the Alien Invaders). Other love interests include Mary Jane, Rachel, and even a potential romance with Velma in Mystery Incorporated, but his most iconic romantic interests often involve alien/supernatural characters or those who appreciate his quirky nature.
As a result of thr Terror Wood, Daphne thought Shaggy was Fred, and kissed and slept with him. They both were confused when realising Fred was Shaggy. Twice after, Shaggy stated he liked it.

Daphne and Eloise will never be best friends, but they are forever and always sisters, and that means something to both of them.
Fred Jones
Fred usually takes the lead in solving mysteries, often pairing with Daphne and Velma. He is sometimes shown in a romantic pairing with Daphne.
Shaggy has been illustrated with brown, blonde and red hair at times ; using the yellow(as opposed to the brown) also allows for him to stand out from Scooby on the blue background.
Yabba-Doo is a white Great Dane. He looks like his brother, Scooby, but has white fur instead of brown fur and it is visibly more unkempt than his mystery-solving brother.
Did the Scooby Doo gang include a sixth member? No, there was no sixth member of the Mystery Inc. gang.
While the Mystery Inc. Fred is the most bluntly Autistic there is Autistic coding for him in others “projects” too. Scooby Doo projects each tend to focus on one member of the gang, resulting in each of them having a refined set of character traits and stories.
The subject of Velma's affections is an original character named Coco Diablo, who is also bespectacled with a turtleneck like Velma's, and is also apparently the leader of a crime syndicate the Mystery Gang is pitted against.

Velma and Shaggy are initially a couple, but they have some conflict and later breakup, as Shaggy chose his friendship with Scooby over his relationship with Velma. Though Velma was initially extremely offended, she eventually came to terms with Shaggy's decision.
Furthermore Shaggy has 3 girls with his wife Rebecca (2nd pic): twins named Kelsey and Madison (6th pic), born in 2008, who live in Shaggy´s second home Broward County, Florida as well as a bit elder daughter, named Sydney (5th pic).
