1.
you have to create new folder inside res folder
2.
In Android Studio, at the top right where you have your project structure and Android View is selected, choose "Project", and you will be able to see the full hierarchy of your project. From there you can achieve what you are trying to do.
3.

Since these are folders, you can always use Windows Explorer to add them.
In Android Studio, the Project Window is currently in the default Android View. If you want to see the physical directory structure, you need to change it to the Project View by clicking on the drop down menu at the top of the Project Window.

Now you can add folders any where you want similar to how you do in Windows Explorer.
