The Switch Lite is designed for handheld gaming, so shared multiplayer on one Switch Lite is problematic. Local and Online Mulitplayer over Wi-Fi is no problem, but because you can't connect the Switch Lite to the TV and there are no removable remotes, shared Switch Lite multiplayer is not easy. You could buy a Switch Lite stand and connect other controllers and play like that, but the small 5.5-inch screen means that the standard Switch is a better option for multiplayer.
