Primula species enroute Mt. Mukut

Could the members of this esteemed group help identify these wild Alpine blooms. These were clicked by the Indo-Tibetan Border Police's Constable Biman Biswas enroute to the ITBP's expedition in June 2016 to Mt. Mukut (7,153-metre summit), Chamoli, Uttarakhand. 
The blue flowers are Primula species while yellow flowers are of Sedum species.
Very difficult to see any details
