Hello @nestorjosue and welcome to the Instructure Community. The Canvas LMS Mods browser extension can help you with the sort options on the People page that are not native to Canvas. For the alphabetical sort order on the Grades page, check the options for sort that are described on the Canvas Guides page, in particular its section on Display Name Order. It looks like the free-for-teachers instance does not have the option to split the student names.
