Even back then, Toys R' Us was famous for it's almost overcompensating attention given to the Barbie line. No other franchises got their own aisles, at least not for many consecutive years. Still, Barbie is interesting if only because it's a window to all the other pop culture shenanigans going on at the time. The dolls were always upgraded to fit the latest trends, with the proof behind provided by the glance at Barbie's 'Rockers' series. Makes me very glad that I was young enough to get away with claiming to be an 80s toy connoisseur and not an 80s fashion expert.
She-Ra, recently thrown into the mix as the female answer to the Masters of the Universe line, was riding a good wave of popularity at the time, even though it was going to be cut short ultimately. There's several parallels to the He-Man collection shown even in the few pics above, most notably the girl's version of Castle Grayskull, She-Ra's 'Crystal Castle.' The figures themselves were 5" tall or so, coming with swords and completely out-of-scale hairbrushes in pastel colors. Nowadays, their worth is comparable to MOTU's prices, but offset by the fact that there were far fewer Princess of Power dolls. Discrimination works on all fronts.
