Hip stretches included on this page can be used to stretch hip flexors, hip extensors, adductors and abductors.
A simple stretch for the hip extensors is low lunge. In this case the hip extensors of the front leg are stretched. This pose could also be also be used as a gentle stretch for the hip flexors of the rear leg.
You could also use low lunge to strengthen your shoulders and arms, for example by bending your arms push-up style to sink your chest.
In most cases, glute stretches stretch the back of the hip with the leg externally rotated to target the glutes and even the piriformis.
In terms of moving the thigh outwards and inwards relative to the pelvis, the adductors (which move the legs inwards) are located along the inner thighs while the abductors (which move the legs outwards) at situated between the top of the pelvis and the top of the thigh bone at the side of the pelvis.
Where the gluteus maximus works mainly on the back of the hip, the gluteus minimus and medius are situated at the side of the hip.
Doing lunge type poses with the leg turned out is one way of stretching the glutes.

Another way to stretch the sides of the hip are in poses like standing side bend where you push the hips to the side.
In this case it is the glute of the outer most leg that is stretched.

You can do this with hands on the floor (which can be helpful when getting into the pose) or with hands lifted.
