When Chin mentions his adventure with MacGyver from the crossover "Flashlight (2017)", Grover is amused about his first name "Angus". In the original MacGyver (1985) series, Mac's first name was rarely ever mentioned, and wasn't even revealed until the show's seventh season.
The title in english translates into "Exodus"
At the beginning of the episode, when Kamekona and the scout are selling McGarrett cookies, the troop number on their uniforms is 1138. This number may be a reference to George Lucas' "THX 1138" - the number 1138 pops up in many TV shows and movies.
