No-one else who was over 20 at the time of the Numbers 14 rebellion. This is made clear in the following verses.
Say to them, ‘As I live, declares the LORD, what you have said in my hearing I will do to you: your dead bodies shall fall in this wilderness, and of all your number, listed in the census from twenty years old and upward, who have grumbled against me, not one shall come into the land where I swore that I would make you dwell, except Caleb the son of Jephunneh and Joshua the son of Nun.
See also Numbers 26:63-65; 32:11-12.
That means that there were only two people (Joshua and Caleb) aged over 60 when the Israelites crossed the Jordan River and entered the promised land.
