Location found

The graduation gown in the second image clearly shows the logo and name 'Women's University in Africa,' which is a specific and unique institution located in Harare, Zimbabwe. This provides a precise landmark match. The environment in the first image with rocky terrain and vegetation is consistent with some areas around Harare. The third image inside an airplane does not provide location clues but does not contradict the other evidence.

While the graduation ceremony is confirmed for Lusaka, it's possible the individuals are from another major Zambian city, such as Ndola in the Copperbelt Province. The photo taken amongst the rocks could potentially be from a different region within Zambia. This is a low-confidence alternative, acknowledging that the photos might not all be from the same immediate area.

The landscape in the first image, featuring prominent granite kopjes, is highly characteristic of neighboring Zimbabwe, especially the region around Bulawayo and Matobo National Park. This candidate considers the possibility that the individual is from Zimbabwe and was studying at the University of Zambia in Lusaka. However, this is highly unlikely given the presence of a Lusaka-based photographer in the graduation photo.
