Riley Jensen is sister of Alex Jensen.

Riley and Alex share both parents, so each is one step up to their most-recent common ancestor (mom or dad). Same generation, distance 1 each → siblings.

Both go up 1 step to the same parents (Linda Cole & spouse). Same generation, distance 1 each → siblings.
