I actually chose Andrea to be my favourite, not necessarily personality-wise, but she's the most unique of the figs, and her white-and-green outfit simply looks the best out of the bunch. I would love to have a dark-skinned female minifig in my collection, but for now Andrea will have to do...

While naturally most of the minidolls in the Friends line are versions of the (so far) five Friends around whom the line is based, a few other characters are included for them to interact with - Olivia's parents Anna and Peter (with Olivia's House), Sophie the veterinarian (with Heartlake Vet), and Marie the barista. And yes, Marie is indeed blonde (but otherwise does indeed look remarkably like Olivia).
There's also Sarah the hairdresser from the beauty salon set.

But she seems to be Andrea's clone anyway, with the same hairpiece as Sophie. In fact, only Anna & Peter's heads seem to be different from the five "friends".
Here's the pics of the rest of the mini-dolls:
