1.) Weakened or not Alduin still had the strongest thu'um of all, that is why the others followed him. The Dovahkiin was able to defeat Alduin making him the most powerful dragon. The Dovahkiin was destined to defeat Alduin so I believe he was destined to be the most powerful Dragonborn.

2.) True, but the Dragon Priests were very powerful, and Vahlok was powerful for a Dragon Priest.

"The two fought a mighty battle that lasted for days, each hurling terrible arcane energies and thu'um shouts at the other.

So great and terrible were the forces unleashed in this contest that Solstheim was torn apart from the mainland of Skyrim."

-The Guardian and the Traitor

3.) Yah I can't honestly be too sure about Alessia as she was only given her power right before she was about to die. But supposedly it was given to her by Shezarr or Akatosh himself, I felt like that had to count for something, though I wouldn't doubt it if Reman was more powerful.

4.) Pelinal is much more likely just a Shezarrine as I've seen many refrence to this.

"he stood with white hair gone brown with elfblood at the Bridge of Heldon, where Perrif's falconers had sent for the Nords, and they, looking at him, said that Shor had returned"

The Nords believed that Pelinal was Shor.

- The Song of Pelinal, Book IV

"Still others, like Fifd of New Teed, say that beneath the Pelinal's star-armor was a chest that gaped open to show no heart, only a red rage shaped diamond-fashion, singing like a mindless dragon, and that this was proof that he was a myth-echo, and that where he trod were shapes of the first urging."

-The Song of Pelinal, Book VI

Obvious allusional evidence that Pelinal is a Shezarrine.

Though I guess it is possible that he still could be a Dragonborn as "singing like a mindless dragon" seems to be refrencing Akatosh who is technically an insane dragon.
