It is well-known that for topological dynamical systems $\epsilon$-stable sets have a deep connection with the topological entropy of the systems. In the present paper, we investigate the relationships of upper metric mean dimension with potential, Bowen upper metric mean dimension with potential, packing upper metric mean dimension with potential between the blocks of $\epsilon$-stable sets, $\epsilon$-stable sets, the dispersion of preimages of $\epsilon$-stable sets and the whole phase space. As applications, we reveal that three types different of entropies, tail entropy, preimage neighborhood entropy and topological entropy in topological dynamical systems, have the same metric mean dimension; We also establish some new double variational principles for mean dimension and upper metric mean dimension in terms of $\epsilon$-stable sets.
