Yes, location often vital for id in a country like Ecuador
I'll make some suggestions: 1 Black-eared Hemispingus?, 2 (and maybe 4 and 5?) Golden-naped Tanager. Bird in post #2 Black-capped Tanager? .....
And .. when it comes to South America, there are actually very few people on Birdforum who help on the ID forum, with enough experience that you might be tempted to call them experts... compared to every other region.
I recently posted some relatively clear images of a pewee (Blackish or Smoke-coloured), hoping for a confident answer ... and didn't get one.
