    The current investigations present the numerical solutions of the novel singular nonlinear fifth-order (SNFO) system of multi-pantograph differential model (SMPDM), i.e., SNFO-SMPDM. The novel SNFO-SMPDM is obtained using the sense of the second kind of typical Emden-Fowler and prediction differential models. The features of shape factor, pantograph along with singular points are provided for all four obtained classes of the SNFO-SMPDM. The extensive use of the singular models is observed in the engineering and mathematical systems, e.g., inverse systems and viscoelasticity or creep systems. For the correctness of the proposed novel SNFO-SMPDM, one case of each class is numerically handled by applying supervised neural networks (SNNs) along with the optimization of Levenberg-Marquardt backpropagation scheme (LMBS), i.e., SNNs-LMBS. A dataset using the traditional variational iteration scheme is designed to compare the proposed results of each case of SNFO-SMPDM. The obtained approximate solutions of each class using the novel SNFO-SMPDM are presented based on the training (80 %), authentication (10 %) and testing (10 %) measures to evaluate the mean square error. Fifteen numbers of neurons, and sigmoid activation function are used in this SNN process. To authenticate the competence, and precision of SNFO-SMPDM, the numerical simulations are accessible by applying the relative measures of regression, error histogram plots, and correlation.
