Upvote:4
Revelation gives us a hint:
Whoever has ears, let them hear what the Spirit says to the churches. To the one who is victorious, I will give some of the hidden manna. I will also give that person a white stone with a new name written on it, known only to the one who receives it. (Revelation 2:17)
However, that new name is a secret name, not known by anyone except the person and the Lord. As for names to be shared between people in Heaven, I must defer to others as I do not know.
