Harry's father, James, Lupin, Peter, and Sirius Black were friends as teenagers. They fell out with Snape.
As adults, James, Lupin, Peter, and Sirius confronted Voldemort. Peter betrayed James, resulting in the deaths of James and Lily, and then faked his own death. The public still believes the traitor was Sirius.

Lupin is secretly a werewolf

Sirius can transform into a dog and Peter into a mouse (they are Animagi but they never reported it, so it is illegal)

Peter Pettegrew is alive, disguised as a rat. He hasn't been human again in 12 years, he's such a coward.
