This was already explained, Beating a primal will give you a single-use ability to summon the primal (only one can be summoned per server at a time, and it will be visible to the entire server like the eclipse when ifrit is summoned) after you summon it, you have to beat it again to gain the right to summon it again.

As for the 12 deities, a deity is a synonym for God, It is highly doubtfull we will be allowed to summon anything that is a single entity, We were already told that we would be allowed to summon minions of the primals as they are multiple entities, I can't confirm this next part but i think I heard somewhere that one of Leviathan's Minions will be Shiva, and one of Garuda's minions will be Carbuncle.
