Abstract: Regular polygonal complexes in euclidean $ 3$-space $ \mathbb{E}^3$ are discrete polyhedra-like structures with finite or infinite polygons as faces and with finite graphs as vertex-figures, such that their symmetry groups are transitive on the flags. The present paper and its predecessor describe a complete classification of regular polygonal complexes in $ \mathbb{E}^3$. In Part I we established basic structural results for the symmetry groups, discussed operations on their generators, characterized the complexes with face mirrors as the $ 2$-skeletons of the regular $ 4$-apeirotopes in $ \mathbb{E}^3$, and fully enumerated the simply flag-transitive complexes with mirror vector $ (1,2)$. In this paper, we complete the enumeration of all regular polygonal complexes in $ \mathbb{E}^3$ and in particular describe the simply flag-transitive complexes for the remaining mirror vectors. It is found that, up to similarity, there are precisely 25 regular polygonal complexes which are not regular polyhedra, namely 21 simply flag-transitive complexes and $ 4$ complexes which are $ 2$-skeletons of regular $ 4$-apeirotopes in $ \mathbb{E}^3$.
