In [2] and [7], Baran defined various generalization of the separation properties T-3 and T-4 for topological spaces to arbitrary topological categories. The main objective of this paper is to characterize each of the different notions of regular and normal objects in the category of proximity spaces as well as to examine how these generalizations are related.
