Recent STAR measurements of azimuthal anisotropy have focused on the use of two- and multi-particle correlations as probes for model constraints for the temperature dependence of the specific shear viscosity $\eta /s$ and the initial-state structure of the collision zone. We will discuss and summarize recent two- and multi-particle correlations measurements of $v_n$ $(n>1)$ , dipolar flow $v_1^{even}$, and $⟨cos(n{\phi }_1+m{\phi }_2-(n+m){\phi }_3)⟩$, as a function of centrality, transverse momentum ($p_T$), and pseudorapidity ($\eta$) for $Au+Au$ at ($\sqrt{s_{NN}}=7-200$~GeV;{em BES-I}), $U+U$ at ($\sqrt{s_{NN}}=193$ GeV) and $Cu+Au$ , $Cu+Cu$ ,$d+Au$ ,$p+Au$ at ($\sqrt{s_{NN}}=200$ GeV).
