Galadriel: with what was each member tempted?

[Inziladun]

An interesting topic!

I agree that Aragorn's weakness might be Arwen, along with the recovered kingship of Arnor and Gondor, with the Ring's power giving certainty of easy victory.

With Gimli, might it be using the One as a foundation for enormous wealth and prestige among his people, as the Dwarves once used the Seven?

Merry and Pippin are a bit tricky.

Merry might want to use the Ring to show he isn't just mere "baggage", as at the time of the Lórien stay, he hadn't yet had the chance to show his mettle.

Pippin may have been similar, with the added push of being the youngest of the Company, not wanting to be seen as the child.
