Navigate to your SharePoint Online site where the group is used, Click on Site Settings gear >> Click on Site Settings from the menu.
From the Site Settings page, Click on "People and groups" under Users And Permissions section.
On the Left navigation menu, select the group from which you'd like to remove the users.
Tick the check box next to the user(s) you want to remove.
