The only one there that really interests me is Melchizedek.
It would make sense that he might be Shem, as Shem was still alive and not that far apart, generationally speaking from Abraham.
That's always been my guess as to who he was...
Shem lived long after the death of Abraham. And wouldn’t it make sense he is the Priest since he’s the oldest male of the Semite family? One Jewish story is when Rebekah goes to inquire about the twins in her womb she goes to Shem.

...Wisdom and righteousness didn’t begin at Sinai. One need look no farther than the Chumash to see that Mankind had mitzvot and Divine wisdom before the giving of the Torah...
...it’s quite rational that academies always existed for the study of the seven Noachide laws and the prophetic wisdom of the time.
Therefore, Noah’s son Shem and Shem’s grandson Ever directed an academy in Be’er Sheva where these traditions were studied and upheld in the hope that they be passed on to future generations...
..he might be Shem
There’s also Larry or Curley
Like the thunderous utterances that John was forbidden to write down in Revelation, God has his secrets and only will give us occasional hints. There might even be folks alive even now like the prophet and prophetess who spoke of Christ’s mission on the 8th day after his birth, whom God has given much truth but have been told to keep silent but to act in certain ways...much like oars that steer the boat of history thru it’s various currents and eddies.
If you want to understand Melchizdek and its priestly order, look at the life of Christ and see how he acted. Mankind was condemned under the Mosaic law, but Christ, the fulfillment of that law, came to save it.
The law condemns a man who sins and leaves him no relief, even should he repent...but Christ saves a man and wipes the slate clean.
Melchizidek is a priestly order dedicated to the reclamation of men and to restore them to fellowship with God. The law is not set at naught but instead it becomes alive via the Holy Spirit in each regenerated man and operates via Melchizidek normatives not Mosaic normatives or more simply put, with the mind of Christ!
Such regenerated men operate via the two greatest commandments...to Love God with all that they are and to love their neighbors as themselves. God is Love!
