Conveniently, most Final Fantasy games have, at the most, only three female protagonists.
The Enneagram of Personality is a model of human personality which is principally understood and taught as a typology of nine interconnected personality types. The main female protagonist of each Final Fantasy game. The Enneagram types are:
As Type One, Yuna is Rational, Idealistic, Principled, Purposeful, Self-Controlled, and Perfectionistic.
As Type Two, Tifa Lockhart is Caring, Interpersonal, Demonstrative, Generous, People-Pleasing, and Possessive.
As Type Three, Lenna Charlotte Tycoon is Success-Oriented, Pragmatic Type: Adaptive, Excelling, Driven, and Image-Conscious.
As Type Four, Terra Branford is Sensitive, Withdrawn, Expressive, Dramatic, Self-Absorbed, and Temperamental.
As Type Five, Princess Garnet is Intense, Cerebral, Perceptive, Innovative, Secretive, and Isolated.
As Type Six, Lightning Farron is Committed, Security-Oriented, Engaging, Responsible, Anxious, and Suspicious.
As Type Seven, Rinoa Heartilly is Busy, Fun-Loving, Spontaneous, Versatile, Distractible, and Scattered.
As Type Eight, Ashelia B’nargin Dalmasca is Powerful, Dominating, Self-Confident, Decisive, Willful, and Confrontational.
As Type Nine, Rosa Farrell is Easygoing, Self-Effacing, Receptive, Reassuring, Agreeable, and Complacent.
How do each of them relate to their female compatriots? Through their wings.
First, a couple of key terms:
Integration – When they feel more secure and in control of a situation. When they are healthy.
Disintegration – When they are under increased stress and pressure— when they feel they are not in control of the situation. When they are unhealthy.
Wings – One of the two types adjacent to it on the circumference of the Enneagram.
Yuna identifies well with Rikku when she’s healthy, but Lulu or Paine when she’s unhealthy.
Tifa identifies well with Aerith when she’s healthy, but Yuffie when she’s unhealthy.
Lenna identifies well with Faris when she’s healthy, but Krile when she’s unhealthy.
Terra identifies well with Celes when she’s healthy, but Relm when she’s unhealthy.
Garnet identifies well with Eiko when she’s healthy, but Freya when she’s unhealthy.
Lightning identifies well with Vanille when she’s healthy, but Fang when she’s unhealthy.
Rinoa identifies well with Selphie when she’s healthy, but Quistis when she’s unhealthy.

But this is just my interpretation. Maybe you have another? What do you think?
