CLOSED: Help with a trio of Birds

I spotted these three birds at Ausable Marsh Preserve in NY. I'm not 100% on the ID of any of them so any help much appreciated as always:

First bird, no idea on this one apart from some sort of Sparrow?

Second bird: Probably a Song Sparrow but just wanted to double-check.

Third Bird: I thought maybe Nashville Warbler, although it lacks the white eye-ring.

Just found a fourth one: Possibly a Lincolns Sparrow?

#1 - Purple Finch, female / juvenile

#2 - yep

#3 - Common Yellowthroat, female

#4 - another Song Sparrow; the bill is too heavy for Lincoln's. Both the SS are juveniles, so with finer flank streaks than adults (and confusingly like Lincoln's!).

Resin

Thanks Resin. I think I keep seeing juvenile Song Sparrows which make me second guess whether they are SS or Lincoln's. I'll have to keep in mind the bill for future reference.
