Cracking sounds from joints is fine until its painless. Its a normal phenomenon in many people.

Cracking sounds are benign as long as they are painless. If painful meet a orthopaedician. Do exercises within your tolerable capacity but no heavy gym activities like lifting weights or twisting your knees

It's normal most of the time, unless you have family history of osteoporosis. Be sure to take adequate food and calcium supplements. If problem still persists , you may need X-ray to see if there is any osteophytes inside joint or not.
