Sounds quite a bit like a Virginia's Warbler.

Not sure either but I'll take a shot. 1. Orange-crowned Warbler 2. and 3. Warbling Vireo? 4. and 5. Pretty sure on Yellow-throated Warbler

Young Barn Swallows don't have "streamers" on their tails. Young birds are also bigger than adults in most bird species from what I've heard. I'd agree with BARS here.

I don't know what it is about #1, but it doesn't seem like a Brown-headed Cowbird, but I can't think of anything else it could be besides Evening Grosbeak. Maybe it's the short tail and light colored beak?

How about Olive-sided for the past one? I see a "zipper front".

Well the first thing I'd say is that the lighting can make birds appear green, especially if you have lots of large deciduous trees around. Flycatchers get this a lot and that would explain the hovering for a moment (stopping to look at a bug perhaps). Otherwise I'd say it was probably a hummingbird just at a weird angle.

I'd agree with that due to extensive dark below the eye.

Looks right to me!

Yeah I can see Willow here.

Could you explain where the 2 tones of gray were located? Could be a Black backed, American Three-toed, or Hairy Woodpecker, or perhaps a Williamson's Sapsucker.

You got it!

I'm having trouble seeing it but I'm pretty sure it's an Olive-sided Flycatcher.

Yep, Bullock's.

Female House Sparrow.

Looks a bit more like a Song Sparrow to me.
