Help with IDs of some South African birds

[Kitsafari]

I took these photos in Cederberg, north of Capetown in South Africa but need help to identify/confirm the species please!

 

Thanks much in advance!

 

White-throated canary? 

 

Karoo Chat? 

 

Grey-backed Cisticola? 

 

Karoo Chat? 

 

Karoo chat also?

I'll let better birdwatchers than me comment but my initial view is:

1. Streaky-headed Seedeater

2. Karoo Chat 

3. Grey-backed Cisticola

4. Karoo Scrub Robin

5. Karoo Chat

Oh thanks so much @lmSA84 - that streaky-headed seedeater indeed matches the bird! and thanks too for the rest of the IDs.
