Its quite hard to find geodata for Africa. OpenStreetMap have some bits and pieces:
Kinshasa, DRC
I’ve produced these shapefiles that contain vector data for Kinshasa. You probably won’t find this data in other places. It is licensed under the terms of this license – if you distribute this data, you should attribute its creators (OSM) and you should maintain its license.
