As far as God hood goes the ranks go like this:

Demi-God- is reached once one exceeds the ascended rank and is able to feel and manipulate divine energy. 

Minor God- is reached once a demi God obtains  enough divine energy to advance. It also requires certain mastery of an element to advance into. 

High God- to reach this rank you need complete mastery of at least one element, you will be shown a list of laws to govern over and must train the adequate elements to advance.

What this is saying is that to advance from over God to the next rank you must reach the necessary mastery in the manipulation of an element, not everyone can master all the elements as some people just have low or no affinity towards more than one element. So not everyone could be the, let's say, the God of time as it requires mastery of all basic elements plus the addition of void. 

This brings me to my next info dump. There are 6 basic elements that humans can wield, Earth, water, Wind, fire, dark, and light. But as states before not all of them have affinity for certain types. However, these are just the basic elements, with enough comprehension of these elements one can create their own element.

What I mean is that you could be a lightning Mage should you either reach a certain mastery in the wind element or if you reach an understanding to the concept of the element. The final option is to get a divine imprint from the dragons, if their master could manipulate the void, they would receive minor affinity with the void element.

The last rank of gods is Sovereign

Sovereign- to reach the sovereign rank one must completely master a law, and possess astral energy, there can only be one sovereign at a time. Should you reach sovereignty you must either submit to the current sovereign or battle to the death.

To put it simple, there levels of god hood. The levels go like this:

A case of theft: this story is not rightfully on Amazon; if you spot it, report the violation.

Reach a certain level of power (demi-God)

Then 

Become one of many rulers of an element ( can be more than one) (High God)

Finally there is

The representation of of an Idea/element. There can only be one. By this I mean that they become the figure head, for example there are many gods that rule fire, but there is only one God of fire ( the sovereign) as they have the highest understandings in this element. 

The current 5 gods, or rather sovereigns 

Are:

Astra- Goddess of light, depicted as a 22 year old woman with pale white skin, golden hair and eyes and golden wings. She was the first God made by Atlas and as a result is more powerful.

Ryze- God of fire, depicted as an 18 year old short tempered man with a tab, fire red hair and Crimson eyes.

Talia- goddess of darkness, depicted as a 21 year old female with pale white skin, waist long dark black hair and eyes

Faro- God of magic/mana, the only current God that represents an idea, but due to being created 10,000 years after the rest of the gods he is weaker. He is depicted as a humanoid entity made of mana, often sporting a black wizard hat and cane.

Kane- God of water, He is often depicted as a tall, spake skinned man with sky blue hair and pupils.

Between the sovereigns there is a big difference of power between representation of element and idea. representation of idea is usually stronger than element, but both require insight into laws of the universe to accomplish.

When a god reaches sovereign level their body goes through a change to bring their body closer to that element/law, for example if you become the representation of fire you will receive attributes of fire, such as red hair, maybe short temper, and explosive outputs of power.
