Just to start the ball rolling on identification I offer the following:
1. The uniform of the soldiers in your second pic (from RP) is from the Royal West Kent Yeomanry; the identifying features being the bandoliers and the spurs. Thanks to my mate, grandarog for the identification...
Dave - unfortunately your friends identification as to regiment is incorrect. They are Royal Artillery (probably RFA, but not impossibly RGA, RHA, etc). Their cap badges are very distinctive, as is their wearing white lanyards on the left shoulder. The 1903 Pattern bandoliers and spurs are common to many regiments, and are nothing specifically tied to the RWKY:
