The Famous Five, as described in the linked article, were four cousins and a dog in a series of children's books by Enid Blyton. These days, they are a pretty soft target for satirists. They were and are phenomenally popular in the UK. Another famous character, for younger children, was Noddy, who invariably met his friend Big Ears.
The Famous Five were the sort of kids who could only have been invented in their age (late forties/early fifties). They attended boarding schools and spent all their holidays together. Invariably they ran into a wicked criminal, whom they eventually helped to get exposed.
They never said rude words, ("bother" and "blow" are the closest to expletives), never smoked a cigarette and never drank anything stronger than ginger beer. After being threatened with a gun by a dangerous criminal, they would invariably say something like, "I was a little bit nervous at first, I don't mind telling you. But looking back, it seems jolly exciting, don't you think?"
If you take into account that the oldest must have been twelve, when they started, by my reckoning, they must have been in their mid twenties by the time they left school. In those days, that was no problem for a children's author, because it was before sex was invented (I believe).
To a Brit, the books are quite funny. They are trite, have barely any adjectives and have characterisation which would barely distinguish a horse from a rabbit. To Americans, they must seem rather bizarre.
