We study supersymmetric extra U(1) model with S4 flavor symmetry. The flavor symmetry not only stabilizes proton but also suppresses the flavor changing processes without raising the supersymmetry breaking scale. After the flavor symmetry is broken, the Yukawa hierarchy is realized by the Froggatt-Nielsen mechanism. The relevant Peccei-Quinn scale for axion dark matter: (fa)/(MP)∼ 10-5 accounts for small up quark mass. The muon mass scale: (mμ)/(MW)∼ 10-3 is related to the O(10-6) mass degeneracy of right-handed neutrinos, from which we can identify the relevant scale of right-handed neutrino mass for baryon asymmetry of the Universe as TeV. Due to the existence of the extra higgsinos, the discrepancies of the anomalous magnetic moments of the muon and the electron between the standard model predictions and the observations are explained by the chargino-sneutrino contributions simultaneously.
