Will hard nose tip from tip cartilage graft soften with time?

One of the most common things that occurs after revision rhinoplasty is that the tip is permanently stiffer than before  revision. This is expected, since during revision rhinoplasty the cartilage grafts added to insure long term structural stability are intended to stiffen the nose. The good news is that the nose will continue to soften over the first year or two. Since you had surgery only six months ago, your tip should be softer than it is as you continue to heal. How much softer? There is no good way to predict. Just be patient and let the healing process continue.
