Nice find!
The harder to find petites like the Twinkles (top 3) go for about $12-15. Bright Sight and Glowing Magic tend to go higher.
Next 2 with the molded hair are part of the 10 pack parade set and go for around $4-5. The mommy charm would probably be around $4-8.
The last is a ponytail petite and they seem to be the most common at $4-5.
