In this paper, we consider the conformable resonant nonlinear Schrödinger equation (CRNLSE) incorporating Kerr law nonlinearity and provide some new analytical solutions. Three analytical methods such as the Exp-function method, modified 
-expansion function method, and -expansion function method are utilized to handle this problem. These methods yield various innovative and fascinating solutions, including trigonometric, exponential, periodic, bright, singular, dark, and rational solutions, as well as their constraint conditions. Moreover the modulation instability (MI) of the consider model is also investigated. For each solution discovered, 2D, 3D, and contour plots are also sketched to clarify their physical configuration. The reported solutions enhance the previously established results. The solutions demonstrate that these methods are efficient and effective for locating traveling wave solutions and could be a beneficial tool for handling other complex nonlinear partial differential equations (NLPDEs) emerge in diversified scientific fields such as hydrodynamics, nonlinear optics, nonlinear fibers and plasmas.
