The second picture is Angel Cake wearing Strawberry Shortcake's outfit, so she might not be worth as much as she normally would be due to not having the original outfit she came with. Top doll is SSC herself and third doll is Blueberry Muffin. Blueberry is missing her hat and shoes, SSC is complete except for pet but is the most common doll. Last time I sold these dolls I got between $3 and $5 each for them.
Your fourth doll is one of the twins Lem and Ada...I believe that one is Lem but I'm not positive. It took me a while to find mine and those booties often get lost. I'd say that one is worth a bit more, perhaps $8-10, but that's simply an educated guess.
