History Does anyone recognize any famous faces in these photographs of Panthic leaders from the 20th century?

[SikhHeritage]

Hello all, I have been a long-time lurker for over a decade and this is my first post here. I came across some old photographs of Sikh religious/political leaders and/or luminaries from the 20th century and I am kindly asking for assistance with identifying who is who in the pictures so that I could take the liberty of labelling/marking each person in the photographs correctly as I archive them for future generations. Thank you!
