  We study supersymmetric extra U(1) model with $S_4$ 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: $\frac{f_a}{M_P}\sim 10^{-5}$ accounts for small up quark mass. The
muon mass scale: $\frac{m_\mu}{M_W}\sim 10^{-3}$ 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.
