So im trying to remember these books i read when i was about 12. So the year wouldve been 1985, or so. It was about either 4 or 5 teenage girls. Each had their own book and then i believe there was an end with all together. ” i think” but all book titles were JUST the girls name. One was a runaway. Could you please try to hekp me. Ive went down a rabbit hole

Probably not, but maybe the Whitney Cousins series, by Jean Thesman.

Could it be the Orphans series by V.C. Andrews?

The Sisters series by Marilyn Kaye? The girls’ names/titles were Phoebe, Cassie, Daphne, and Lydia.
