Sounsyy will be in here soon to clear this all up definitively, but in brief, as myahele said, the Xaela have a diverse set of beliefs corresponding to their individual tribes/clans. You can find all the blurbs on the Xaela tribes here.
As for the Raen, as far as we can tell, their religion seems very much like Shinto, which fits with their heavy Japanese flavor. Sounsyy makes a compelling argument based on flavor text from the NIN questline that they worship the elementals, similar to the Gridanians.
