I define high-altitude species as those occurring at least 4300m if not 4500m and above. This flower is definitely a Geranium - there are 2 or 3 candidates but unless I know what the leaves are like, it is difficult to be sure. PLEASE, each time you post, provide an approximate elevation (exact not necessary), approximate location in terms of nearest village, pass, lake or whatever and DO ALSO photograph the leaves (foliage) as well as flowers - otherwise it can be IMPOSSIBLE to arrive at a definite identification. Ideally, take SEVERAL photos per specimen showing flowers (front and underneath), foliage (top surface and underneath), habitat shot and habit of plant - I realise this requires greater effort but once a methodical approach is adopted, it is straightforward to do and does not take that long (though hard-going at extreme elevations.....but having taken the time, effort and expense to get to these lovely places, worth getting the most out of it and helping the study of Pakistan flora); nowadays with digital cameras and small memory cards (which can accept large numbers of images) and small batteries, this can readily be done. When I began exploring the Himalaya in the 1980s, one used slide-film, which was expensive, so only 1 or 2 photos could be taken per plant and a tripod plus macro-lens was needed for close-up images of flowers. That has all changed. If anyone reading this is heading to the Himalaya in the coming years and would welcome further advice about securing a good set of images of the flora seen (sufficient to enable me to provide identifications), do get in touch.

In the past it was ESSENTIAL to collect a dried, pressed specimen of each plant to have it reliably identified at a herbarium - where the specimens could be examined close-up. I realise you trips were not scientific expeditions but I am sure you will be pleased that your photos can be put to good use.
