The objective of this article is, first, to introduce and investigate the notions of supra $q$-regular and supra $q$-normal by using the concepts of $q$-regularity  and $q$-normality. Second, to introduce some types of supra $q$-regular and supra $q$-normal continuous mappings and investigate some properties and point out their main features of them. Finally, we introduce and investigate supra $q$-regular (resp; supra $q$-normal) homeomorphism and supra $q$-regular (resp; supra  $q$-normal) irresolute map also supra $q$-regular (resp; supra $q$-normal) contra continuity map and investigate some properties of these mappings with several examples are presented.
