We investigate spin and valley symmetry-broken fractional quantum Hall phaseswithin a formalism that naturally extends the paradigm of quantum Hallferromagnetism from integer to fractional quantum Hall states, allowing us toconstruct detailed phase diagrams for a large class of multi-component states.Motivated by recent experiments on Graphene aligned with a Boron Nitridesubstrate, we predict a sequence of transitions realized by increasing themagnetic field, starting from a sub-lattice polarized state to a valleycoherent Kekule charge density wave state and further to an anti-ferromagneticphase. Moreover for filling fractions such as $\nu=\pm 1/3$, we predict thatthe system undergoes a transition at low fields, that not only differ by thespin-valley orientation of the fractionally filled flavors but also by theirintrinsic fractional quantum Hall nature. This transition is from aLaughlin-like state to a two component Halperin-like state both with a chargedensity wave order. Moreover for $\nu=\pm 1/3,\pm 2/3$, we predict a "cantedKekule density phase"(CaKD) where the spinors of integer and fractionallyoccupied components have different orientations in the valley Bloch sphere, incontrast to the Kekule state for the integer quantum Hall state at neutralitywhere both occupied components have the same orientation in the valley Blochsphere.
