King Zhaoxiang of Qin
Because King Zhaoxiang had not yet legally come of age (traditionally at the age of 20), his mother, who was now known as Queen Dowager Xuan, became the regent. She was supported by her brothers, Wei Ran and Mi Rong (羋戎), as well as two other sons, Prince Yi (公子悝) and Prince Fu (公子巿), the four of them collectively known as the "Four Nobles" (四貴).
Queen Bian
Shortly after Qifu Gangui became king in 388, after the death of his brother, the founding king Qifu Guoren (King Xuanlie), he created her empress. Qifu Guoren was not mentioned as having created a empress, but could have. At that point, she was already described of as his wife. However, nothing more is known about her, including whether she was the mother of his eventual successor, his son Qifu Chipan (King Wenzhao). In 394, Qifu Gangui, in a political marriage, married the sister of the Former Qin emperor Fu Deng, the Empress Dongping, as queen, although presumably Empress Fu was deposed and Empress Bian restored after Former Qin's destruction by Later Qin later in 394, for after Qifu Gangui lost his state but restored it in 409, he again created Empress Bian empress. (The succession table below assumes as such.)
