What apostles did not believe that they saw Jesus?
In the end there were no apostles who remained disbelieving, since they actually saw Him, they talked with Him. They also saw Him eat some fish. Thomas and the others with him also saw the scars His body bore from the crucifixion. So, when they literally saw Him for themselves their initial and natural disbelief of the testimony of others turned around. The lingering doubts of some seems inexplicable in light of the actual evidence. This is a testimony to the brutal honesty of the record -even lingering doubts are recorded, a witness against those who were to be the future leaders of the church. Their names however remain unknown.
