Is Polyamory just one girl with many or more a Girl A x B x C thing? So all three love each other?
Polyamory requires everyone to know and approve of the relationship. So it can be one girl with more than one girlfriend, so long as the girlfriends know and approve. Simplest version would be a V-shape, with three girls, two of whom aren't going out with each other but are co-girlfriends of the one at the vertex.
But there are lots of arrangements. The key points generally are more than two partners, everyone is aware of the others and accepts the relationship structure.
Oh, and an open relationship would be different from polyamory, and of course cheating isn't the same thing as either of them.
