The multinucleon transfer reactions $^{124,136,144}\mathrm{Xe}\phantom{\rule{0.16em}{0ex}}+\phantom{\rule{0.16em}{0ex}}^{238}\mathrm{U}, ^{136,144}\mathrm{Xe}\phantom{\rule{0.16em}{0ex}}+\phantom{\rule{0.16em}{0ex}}^{160}\mathrm{Gd}, ^{136,144}\mathrm{Xe}\phantom{\rule{0.16em}{0ex}}+\phantom{\rule{0.16em}{0ex}}^{170}\mathrm{Er}$, and $^{136,144}\mathrm{Xe}\phantom{\rule{0.16em}{0ex}}+\phantom{\rule{0.16em}{0ex}}^{186}\mathrm{W}$ are investigated within the framework of the dinuclear system model. The charge equilibration effects on the production cross sections of exotic nuclei are studied. The neutron-deficient projectile $^{124}\mathrm{Xe}$ is favorable to produce transtarget neutron-deficient nuclei, while $^{136,144}\mathrm{Xe}$ shows great advantages of cross sections for producing neutron-rich nuclei in the proton pick-up channel. Furthermore, the influence of entrance angular momentum on the charge equilibration process is investigated. It is found that in a low angular momentum channel the more profound reconstruction of initial nuclei is noticed rather than peripheral collisions. We predict the production cross sections of several neutron-rich nuclei in the reactions $^{136,144}\mathrm{Xe}\phantom{\rule{0.16em}{0ex}}+\phantom{\rule{0.16em}{0ex}}^{160}\mathrm{Gd}, ^{136,144}\mathrm{Xe}\phantom{\rule{0.16em}{0ex}}+\phantom{\rule{0.16em}{0ex}}^{170}\mathrm{Er}$, and $^{136,144}\mathrm{Xe}\phantom{\rule{0.16em}{0ex}}+\phantom{\rule{0.16em}{0ex}}^{186}\mathrm{W}$. It is found that many unknown nuclei can be produced at the level of $\ensuremath{\mu}\mathrm{b}$ to mb.
