Not many; if any at all; Barbie collectors travel these parts any more. Used to have many knowledgeable people to help folks like you with questions about vintage Barbie. Maybe you have already found the answers, don't know. Sorry for how long it has taken to get a response here, but the holidays are upon us and we are prepping for them.
Not sure how familiar you are with eBay, but as far as values are concerned, it would benefit you to do a search in SOLD listings for these items to see what they have sold for here. Not many people post here, but there are still buyers galore. Once you figure an average of the sales, I think you will come close to a value.
By looking at these pictures, it is difficult to see just exactly what condition the dolls are in, the clothing, and even the case since cannot see the inside. All your items are vintage Barbie. The Barbie in the gold and white striped suit is called "Fashion Queen" Barbie. It is a perk that she has her suit and turban. Can't tell if she still has the blue satin hair band on her vinyl head. Also hard to tell what shape her body is in..ie, scratches, mars, stains, face paint, etc. etc. This affects value too. The 3 wigs are hers. Can't see if there is the variety of wigs or if they are all bubble cuts or what. They are still on the wig stand which is also a perk, but, can they be removed from the stand? In some cases the plastic and vinyl compounds after time, will cause a 'melting' and the wigs are pretty much stuck to the plastic stand. This of course affects value along with if they are all bubble. Should be 3 different wigs and in 3 different colors. Fashion Queen came out in 1962. In 1963, just the head and wigs were sold.
Your bubble cut Barbie looks to be an earlier bubble cut. Can't be certain what color of brunette she is. Sure not black Bubble cuts came out from 1962-67. Most all came in the red helenca suit; yours is wearing the black, which was sold separately. These gals are hard to put a value on since much depends on hair color, lip color, etc and of course condition. Some are valued much higher than others. Best bet again, is to do a search in SOLD listings, note the type of bubble cut and again figure your average.
Another thing of interest, is the doll body itself. Many girls in those days, switched heads on their dolls often. So, much likely the head and body are not perfect matches. So, it is important to see what is written on the bottom side of these dolls. Are they Barbie only bodies or Barbie Midge bodies. After looking at listings with good photos, you will see what I am talking about. There is a difference....Barbie Midge bodies have a larger neck knob, so removing a doll head NOW must be done carefully to prevent neck tears in the vinyl. Warm the head first. Should be no need for you to remove the heads anyway. FQs have very hard heads and suggest leaving that one alone! Neck tears also diminish value as well as green ear, which is a 'tarnish' so to speak caused by leaving the metal earrings in the doll. A reaction of the metal base and the elasticizer or whatever in the vinyl causes this discoloration which is very difficult to remove. A whole class just for that 
The doll case. Again search barbie doll cases for sold values. This case(should be a year on it) would be sometime after 1963 since it is a case for Barbie and Midge. The more common and easy to come by the case, the lesser in value it will be.
Good luck and have fun doing these searches. You will be surprised at what you can learn just by looking.
Happy Holidays and Merry Christmas!
