Simple phobia/specific phobia, social phobia and agoraphobia are indeed all anxiety disorders.
Phobias belong to a large group of mental problems known as anxiety disorders
Phobias can be diagnosed as a disorder themselves, but disorders such as Panic Disorder, Generalized Anxiety Disorder, and PTSD are all often associated with phobias.
People with debilitating anxiety are said to be suffering from anxiety disorders, such as phobias, panic disorders, and generalized anxiety disorder.
Besides anxiety disorders and phobias many psychiatric disorders have anxiety as one of its features. Example: Depressive disorder.

According to the Diagnostic and Statistical Manual of Mental Disorders, phobias are considered to be sub-types of anxiety disorder (psychiatric disorder).
Phobias are under the general heading of Anxiety Disorders. Agoraphobia is not a "stand-alone" codable disorder. It is included under the specific disorder with which it appears. Specific (or simple) phobias to objects or situations can be coded separately.
Anxiety disorders and mood disorders aren't the same. Mood disorders include all affective disorders including anxiety disorders.
Generally speaking, yes, phobias can lead to compulsive disorder. Still, it depends on the severeness of the phobias.
