Moving the hand into a palm-down position involves wrist pronation. This movement is achieved by the pronator teres and pronator quadratus muscles, which rotate the forearm so the palm faces downwards.
Having an opposable thumb is unique.
During a jumping jack, the hip joint is in a position of flexion and abduction as your legs move out to the side and back together. It also experiences some rotation as your feet turn slightly outward during the movement.
Muscles stabilize joint by supporting the movement of the joints. Joint in the bones are not able to move alone. The muscles support weight from applying pressure to the joint which protects the joint from damage.
When you move your lower jaw forward, the joint movement involved is primarily a combination of hinge (rotation) and sliding (translation) movements at the temporomandibular joint (TMJ). This allows for the smooth opening and closing of the mouth.
Joints facilitate movement in the body by connecting bones together. They are supported by ligaments, which are strong connective tissues that help stabilize the joint during movement. The range of motion in a joint is determined by its structure and the type of joint it is.

An exercise like a bicep curl would be an example of a single joint movement. You can also move your thumb by the gliding joint that attaches it to the hand. I'm sure there are many others.

No, a pivot joint and a biaxial joint are not the same. A pivot joint allows only rotating movement around one axis, like the movement of the head from side to side. A biaxial joint allows movement in two perpendicular axes, such as the wrist which can move up and down as well as side to side.
A flexor is a skeletal muscle whose contraction bends a joint. In anatomy, flexion is a position that is made possible by the joint angle decreasing. The skeletal (bones, cartilage, and ligaments) and muscular (muscles and tendons) systems work together to move the joint into a "flexed" position. ...

Bones in a joint move by the contraction and relaxation of muscles attached to them. The movement is facilitated by the friction-reducing synovial fluid in the joint. The type and range of movement depend on the specific joint and its structure.
Synarthrotic-These joints are "fiberous" and don't move a lot.Skeletal sutureAmphiarthrotic-This joint only permits slight movement. RibsDiarthrotic-Freely moveing joint.
