Demigods: Roles of Demigods

                                                                  Q. Can Vishnu be classified as Demigod? (When I am listing all the demigods to these kids)

                                                                  No, Vishnu is not one among the demigods, but is the Supreme Personality of Godhead. The demigods are empowered administrators of material affairs, and are like different assistants or limbs of the Personality of Godhead, something like the different cabinet ministers are to the Chief Executive of State.
