Betula or birch. Possibly Betula utilis, but I don't have my library resources available to me to check what else it might be.
Yes, Betula utilis subsp. jacquemontii at that location. The dark grey log with scaly bark is something else, perhaps Cedrus deodara or a pine Pinus. The pink flowers are Impatiens glandulifera or a close relative.
Grey one could be a Pinus wallichiana, as this seems to be a fuelwood pile and in this region P. wallichiana is widely used as a fuelwood, together with Betula utilis subsp. jacquemontii. cutted pinus wallichiana wood in surface in forest in hilly area..
