Indians- brought, unwillingly on the part of the British, under direct rule as a result of the 1857 rebellion
Egyptians- Never annexed; shared with the French even after the British invasion of 1882
Zulus- Annexed in 1879
Kenyans- Protectorate established in 1895
!Kung- Though most of the tribe live in German Namibia and Portuguese Angola, some were included in the Bechuanaland Protectorate established in 1885 at the request of the Batswana leaders Khama III, Bathoen and Sebele.
San (not including !Kung)- Excluding those living in Namibia, Angola and Bechuanaland, some were included in Zambia (conquered 1897), Zimbabwe (conquered 1895 by the British South Africa Company), Lesotho (made a protectorate at Moshoeshoe's request in 1869), and South Africa (annexed 1806)
Pashtuns- Mostly living in Afghanistan (never annexed by the British despite the successfully prosecuted war of 1878-1881) though some were included in British territory by the Durand Line (negotiated 1893)
Muslims- ? You might mean Zanzibar (protectorate 1890, though the British had been interfering in domestic politics to end the slave trade much earlier), or Afghanistan (see above), or Somaliland (protectorate 1888), or possibly Bahrain (protectorate 1880)
Like I said, for a power "still set on a global empire over nonwhite peoples," the British don't seem to be very active in going out and getting it. They show relatively little interest in increasing their territory up to the 1880s, and after that they're as prone to hand territory back, make it a protectorate, or begrudgingly take over its government at native request as to actively conquer it. Certainly, they don't appear to be a power on the hunt for a justification for territorial conquest, on a par with Lebensraum or Manifest Destiny.
Poor little Britain, forced to conquer the largest empire since the Mongol heyday against her best intentions, and bear that Burden.
