You generally do not remove pictures from the All View. This view will always contain all of your pictures. If you want to delete a picture permanently (including from all albums), then you can use the Delete Picture capability.
Warning: Any pictures that are removed from the All view using the Delete Picture capability are actually deleted from your PC. They can not be retrieved.
If you want to view a subset of your pictures in the All view, then you will need to use one of the filtering options available (although this is just a temporary option). To learn more about filtering, refer to Using Filters.
If you want to permanently group a subset of your pictures, then you should use Albums and Groups to organize your pictures. Refer to Albums and Groups to learn more about how Albums and Groups can help organize your pictures.
