User create its content type
Your question is not clear but I think you want to know how to set the right access to the different Roles


Go to your_site/admin/people/permissions
Search from the successful store content type
For Role 2 check the "Create new content" and "Delete own content"
Click save at the end of page


Now users of Role 2 can create and delete their own content.

You can also create a link for Role 2 users to access their own content.


Go to your_site/admin/people/permissions
Search from the Access the content overview page
For Role 2 check the box for Role 2
Click save at the end of page
Create a menu item and add the link as admin/content
