Need help with identification of Modern Barbies?

Have old Barbies from 60s-80s that I am selling. Have 3 Barbies from early to mid 1980s that I cant identify.

First has button on her back that moves her arms, long blonde hair past her waste, and pink one piece swimsuit with pink ankle length skirt and light coat cover up.

Second is Barbie in a pink dress with white polka dots and birthday gift that says Happy Birthday Barbie--and no, she is NOT the 1973 Sweet 16 Barbie or the 1991 Birthday Barbie.

Third is the Barbie that has the pink makeup case, you can change her makeup and wipe it off, she has 2 toned hair color that is blonde (mostly) with some brown, her dress is white lace long sleeved on top and satin like pink at the bottom.

I have Googled all this info and cant find the names, or the exact year of make, for these Barbies. Though I do know that all 3 of them are from the early to mid 1980's--since that is when my parents bought them for me.

Anyone know these dolls?

Go to Borders or Barnes %26amp; Noble and look for this book: Barbie Doll Exclusives: Identification and Values 1972-2004 by Michael Augustyniak. It should be in the Collectibles section.
