I don't have an exact PC, but Tamara is your highest value one here.
Her curls look good, and you got the pose for her that is unique to ONLY her. (Otherwise, she is in Nikki's pose) She is the only filly with her own pose and also the 2nd one alone to have 3 colors of hair. So there's a lot going for her, style wise.
Chloe & Joelle are the 2 most common FSF when no FeelinFancy. (They lack lace/are originals)
Calla's haircut will take the value down because they're difficult to rehair unless all the hair has gone. (I think she is Glory Purple color, these did share hair tones exactly with MLPs)
Because Chloe has the name cape, she was the 2nd release of Chloe (First release doesn't have name cape ever) but before FF Chloe.
Joelles' curls are going, she should be "poodly" like the Tamara--but collectors don't/can't care after all this time so it'll come down to unfixable rubs to their paint rather than hair quality if all the hair is there.
Advice for the $$?
Turn the Tamara loose on Ebay around Nov/Dec when holiday shopping is really fired up & she ought to really do something if anyone's out bidding at all. That is a GOOD FSF if her paint is still nice. (Cant see in photo) You can also see 'sold/closed listings' for each of their names and see what happened for a PC idea if you weren't looking to sell on ebay but here instead & just needed "ballpark" figures lest buyers go elsewhere.
I love FSF! CG on having these guys & hope they can do well for you,
