1. The Persona is an identity we hold and which we present to the outside world. We may hold several of such: our career role; our role as mother father, son, etc; our political identity, and so on.
2. The Ego is our center of consciousness, our conscious sense of self. Therefore it excludes (although remains influenced by) all of our make-up that is unconscious. Jung says: "So far as we know, consciousness is always Ego-consciousness. In order to be conscious of myself, I must be able to distinguish myself from others. Relationship can only take place where this distinction exists."
3. The Shadow is an unconscious part of the Ego, and receptacle for that which we have for one reason or another disowned or wish to remain out of sight and those qualities that one would rather not see in oneself, as well as unrealized potentials. The Shadow is intimately connected to the Id and its structures, Thanatos and Eros that contain the animal instincts. It's the part of the personality that's forced out of mental awareness by the Ego's defense mechanisms.
4. The Anima is a node of unconscious beliefs and feelings in a man's psyche relating to the opposite gender, the Animus is the corresponding complex in a woman's psyche. As part of the Ego unconscious, these complexes can rise into consciousness when activated by appropriate circumstances.
5. The Self is simply the totality of the entire psyche. It is the function which contains all the other functions and around which they orbit. It may be difficult for the conscious Ego to accept that there may be more to the psyche than that of which it is currently aware.
