I can tell about the first picture that the woman is probable calm because her eyes aren't so close together.She has long upper lips so she tend to be sarcastic and talkative also because I see thick lips. Finaly she is probable less emotional as her thich hair can tell me.
For the man in the second picture I think he tends to be sort tempered because his eyes are close together. He has long upper lips and he is probable sarcastic. The two sides of his face are looking different, so the man tends to be moody.
In the third picture we have a woman with a very balanced face. This means that she is probable a calm, cheerful person.
The last picture is about a sensitive man because of his nice hair. His eyes are not so closed together so he tends to be calm. He has also long upper lips and he is probable a sarcastic type of person.
