More precisely the regeneration relates to the Spirit of Jesus which God sent into the hearts of those under the law so that they might become adopted children of God (re. Galatians: 4 verses: 5 & 6).

This is something which was offered immediately after Jesus physically left those precincts (re. John: 16 verses: 7 & 13). It was to be picked up immediately . . . . in the manner that Paul picked it up. It does seem to be something that happens to you before you die. It does not seem related to after one is resurrected, per say. Except if resurrected means resurrected from being spiritually dead and therefore now awakened to one's own heart or spirit where in the Spirit of Jesus was sent.

Those who follow Jesus in the regeneration are those who discern the Spirit of Jesus within their hearts and are led into all their works by precisely what this Spirit has in mind for one to pray for, say and do (re. Romans: 8 verses: 26 & 27).

At that point Peter was not following Jesus in the regeneration. At that point, Peter was simply following Jesus in the physical. Seems that Peter never followed Jesus in the regeneration. Peter continued to follow Jesus in the flesh (i.e. the physical), even after Jesus physically left those precincts. However Paul came to have communion with and know, Jesus in the regeneration. Paul also followed Jesus in the regeneration.

This means that Peter would not also sit upon twelve thrones, judging the twelve tribes of Israel (re. Matthew 19:27).

Titus 3:5 is talking about how one is justified by Grace and achieve eternal life (i.e. salvation and deliverance), in one current life. (re. Titus: 3 verse: 7).

There will come a day when Jesus will judge all.

Acts 17:31 Because he hath appointed a day, in the which he will judge the world in righteousness by [that] man whom he hath ordained; [whereof] he hath given assurance unto all [men], in that he hath raised him from the dead.

So then, when is the regeneration? It's not about following Jesus in the regeneration in order to be saved. If this verse is related to what we are saying when we talk about the regeneration by the verse that you mentioned, then by then it will be too late.
