Hi @Jangra98
I've looked at the List plugin in the Touch UI granite richtext.js, and I don't see the 3 options you're looking for available in OOTB. You need to write a custom plugin by extending the CUI.rte.plugins.ListPlugin. Please refer to the blog I've written on RTE Plugins for AEM; it has some great information that may help you with some direction.
Thanks
