G1 Pic:
The hat and the saddle are from the Pretty Parlor. Both are not worth much, maybe about 50cents.
http://mylittlewiki.org/wiki/Pretty_ParlorThe shoes are G3, not G1.
The two brushes are probably not worth much either, unless they’re from a rare pony. Try this site to ID combs/brushes:
https://mylittleponyaccessories.weebly.com/The bottle’s also not worth much.
If the diaper and box are in excellent condition, together they’re probably worth a dollar, maybe a little more.
G3 Pic:
I don’t know the G3 loose accessory market at all, if there even is one really. So I’m sorry, no prices.
The long pink comb is G1, not G3.
The raincoat is an exclusive from Disney Build-a-Pony.
http://mylittlewiki.org/wiki/Disney_Build-A-PonyThe large pink brush is probably from one of the oversized So Soft Newborn ponies.

http://mylittlewiki.org/wiki/Crystal_LakeThe green felt skirt and the orange plastic butterfly wings are from the Butterfly Island playset:
http://mylittlewiki.org/wiki/Butterfly_Island_AdventureThe bead clips, the clips with ribbons, and the blue glitter comb are probably from some Styling Ponies(probably at least a few are from Styling Rainbow Dash):

http://mylittlewiki.org/wiki/Mittens_IIThe little pony charms were free bonuses that came in some of the first G3s:
http://mylittlewiki.org/wiki/KimonoI’m not sure who the rest of the combs/brushes are from(it’s HARD matching up G3 combs/brushes to their correct ponies). I think the large blue brush is non-pony though.
I don’t know what that dark purple/magenta thing is.
