Extending from previous research where formation and decay analysis was carried out for even mass nuclei, this investigation includes the fusion-fragmentation analysis of odd mass isotopic compound systems, ${}^{165,167}\mathrm{Tm}^{*}$, formed in reactions induced by ${}^{35,37}\mathrm{Cl}$ projectiles carrying energy spanning the Coulomb barrier region ($E_{\mathrm{c}.\mathrm{m}.}=90$ to 125 MeV), offering valuable insights into the reaction dynamics of these nuclear systems. To analyze the fusion dynamics of ${}^{35,37}\mathrm{Cl}+{}^{130}\mathrm{Te}$ reactions, the energy-dependent Woods-Saxon potential (EDWSP) model is utilized and it introduces alterations in the alterations in the potential barrier characteristics of the fusing nuclei. This results in the reduction of the effective fusion barrier, and accordingly influences the fusion outcomes. In contrast to the one-dimensional barrier penetration model (BPM), the EDWSP calculations yield enhanced fusion cross sections. This augmentation is especially evident in the energy-dependent behavior of cross sections for the selected fusion reactions, both in the near and sub-barrier energy domains. Furthermore, to address the decay of compound nuclei ${}^{165,167}\mathrm{Tm}^{*}$, the evaporation residue (ER) cross sections are meticulously addressed for quadrupole $\left({\beta }_2\right)$ deformed fragments with orientations optimized for hot configurations, using the DCM model. The sub-barrier fusion enhancement in the excitation functions of lighter isotope ${}^{165}\mathrm{Tm}^{*}$ are explored in terms of preformation and penetration profiles. Lastly, comparative studies of odd mass nuclear systems ${}^{165,167}\mathrm{Tm}^{*}$ are carried out with even mass systems generated in Ca and Ni induced reactions.
