Question: are jango fett and boba fett mandalorians?
Answer: Yes, both wear the armor of the planet Mandalore. But Boba Fett is not, technically, a true Mandalorian. In Star Wars: Episode II – Attack of the Clones, George Lucas establishes that Boba Fett is a clone of the Mandalorian bounty hunter Jango Fett. Jango Fett raised Boba Fett as his son on the planet of Kamino.
