I assume you are using the Remote Templates example demonstrated here: http://docs.telerik.com/kendo-ui/framework/templates/load-remote#remote-templates. Although the example shows how to use a single file, you can still use multiple files and load the ones needed in the pages/views where required. I doubt that this requires any additional code to be implemented, you need to only load the remote templates where you need them.
As for the "editor in asp.net", I am not sure what you aim. If you would like to use those templates as MVC Editor templates, then you should consider using proper partial views. Those remote views cannot be rendered as MVC editor (@Html.EditorFor) or utilize such in the code.
