Okay, I am a Ponyville fanatic, but NOT an expert, so here goes. These may have been released with other sets as well...
Photos 1 & 2:
The butterfly is from MY LITTLE PONY PONYVILLE MEET FOR ICE CREAM WITH TRIPLE TREAT. It sat on top of the ice cream cart. And I think from CELEBRATE SPRING and a few other sets as well.
The orange cat is from TEA CUP PARADE WITH CUPCAKE & STRAWBERRY SWIRL.
The little yellow bird is Pony and is SO familiar but I can't remember off hand what it came from. An Easter set maybe? I can't remember.
The blue bird...I don't think so...not sure about that.
The pink elephant & orange monkey are "prizes" from BUMPER CARS WITH SWEETIE BELLE & ROYAL BOUQUET.
The purple goblet and bowl are Pony, but I'm not sure what they came from. Something similar came with TWINKLE TWIRL'S DANCE STUDIO.

Most of this is not pony. The pink brush is Barbie. The only thing I think is pony is the G3 long blue hair clip.
Photos 4 & 5:
I'm pretty sure most of this is pony, although I'm not sure exactly which set everything is from. Maybe someone else can be more helpful.
Hope this helps
Good luck!
