It's a little strange that no-one has attempted to answer these five queries. I'll give it a try, with the proviso that if someone comes along to say that all my IDs are wrong, at least I will have moved the thread to the top, where hopefully others more capable will have a look.
1. I think this is a juvenile Holub's Golden Weaver. The juvenile looks like the female, but has a pinkish bill and dark eye. The fine black line going backwards from the middle of the rear of the eye seems to be a distinctive feature of this species.
2. This bird is weird. If you look, the bill is deformed - it's crossed at the front. The hairy chest is strange, and I think the reddish colouration on the upper chest and other parts is probably from mud or something like that. I have no idea so ₿60,000 to anyone who gets an agreed ID for this bird (apply to Sam Bankman-Fried for your reward).
3. This is a lark, but it seems to lack the red of Flappet. I wonder if it might be immature Red-capped as illustrated in Birds of East Africa 2nd edition plate 143.
4. I think on looks and location it's Stout Cisticola - online photos show it as having much less of a red wing panel that the illustrations in Birds of East Africa.
5. I think this is just a bedraggled Nothern Grey-headed Sparrow.
I hope this helps or at least gets someone else to look more closely.
