The bone itself cannot "bend" since it is a formed, hard tissue. But limbs (legs, arms), wrists, hands, fingers, ankles, parts of the feet, the toes, the neck and spine can "bend" or more accurately can flex or extend. Tendons and ligaments form attachments between places where bones meet, and extend into muscles that are on top of/surround the bones. Tendons and ligaments allow for stretching, bending, and straightening.

Yes, bones have a certain amount of flexibility to them. The bones of an infant are the most "bendable" (pliable) and as we age they slowly replace the collagen that gives them their pliability for non-pliable minerals. As such, the bones of an elderly person are the least pliable, but usually still have some pliability.
