So do I have to choose a god from the list or so get to make my own god with his own powers and representation? And could you pls explain what exactly you mean by alignment, do mean there personality.

Either is fine. I tried to list as many as I could think of but if you can think of how I haven't your welcome to try for it. For alignment your choices are 
Lawful Good-typically acts with compassion, and always with honor and a sense of duty
Neutral Good-guided by his conscience and typically acts altruistically, without regard for or against Lawful precepts such as rules or tradition
Chaotic Good-favors change for a greater good, disdains bureaucratic organizations that get in the way of social improvement, and places a high value on personal freedom, not only for oneself, but for others as well
Lawful Neutral-typically believes strongly in Lawful concepts such as honor, order, rules and tradition, and often follows a personal code
Neutral-represents Neutral on both axes, and tends not to feel strongly towards any alignment. A farmer whose primary overriding concern is to feed his family is of this alignment.
Chaotic Neutral-an individualist who follows his or her own heart, and generally shirks rules and traditions. Although they promote the ideals of freedom, it is their own freedom that comes first. Good and Evil come second to their need to be free
Lawful Evil-sees a well-ordered system as being easier to exploit, and shows a combination of desirable and undesirable traits; while they usually obey their superiors and keep their word, they care nothing for the rights and freedoms of other individuals and are not averse to twisting the rules to work in their favor
Neutral Evil-typically selfish and has no qualms about turning on their allies-of-the-moment, and usually makes allies primarily to further their own goals.
Chaotic Evil-tends to have no respect for rules, other people's lives, or anything but their own desires, which are typically selfish and cruel.
