Your ids seem correct to me except for the first one.

I suggest you focus on the facts that it has no wing-bars and has a brownish tone above. I think the supercilium is creamy (but there again it isn't really yellow on Yellow-browed!).

Yes, it looks like a Dusky Warbler to me.

You might want to listen out for the call these birds make - a very distinctive 'tack'.
