In this article, we introduce the novel notions of $n$-$CyN\delta$ homeomorphisms, $n$-$CyN\delta$ $C$ homeomorphisms, and $n$-$CyN\delta T_{\frac{1}{2}}$-spaces within the framework of $n$-Cylindrical neutrosophic topological spaces. These concepts extend classical homeomorphisms and separation axioms to the neutrosophic setting, incorporating degrees of positive, negative, and neutral membership. We systematically develop and examine key properties and structural features of these notions, establishing several theorems and results that provide deeper insights into their behavior and potential applications in neutrosophic topology.
