No. Since artifacts (as well as fortresses) are unique like unique characters they follow the same rules, which means that you can't have more than one face up in play or set aside (except captured characters).

Similarly, if you would set aside a unique card (including Artifacts or Fortresses) that you already have in play or set aside area it would get discarded and not set aside.

From the REG (I bolded the relevant section)

Unique Cards
Many cards have the identifier “unique”. Characters are unique if they represent characters in the Bible with specific names, have “The” in the title of the character, or otherwise have a “unique” identifier on the card. All Fortresses, Artifacts, Curses, and Covenants are unique cards.
Players may only control one of each unique card in his territory, set-aside area, or his side of battle.

I believe, as far as the game is concerned, it happens all at once, but I'm not entirely sure.

What is the difference?

If it was one at a time and the top card was unique and the same unique card was set aside already, then the unique card stays on top of the deck, right?

I think if you reveal 2 of the same unique card with 1 Jar, then the second copy would return to deck anyway.

As far as I'm aware (which could be totally off knowing me ), if you reveal something and can't do what the paired ability says, it returns to previous location.

How to Play
When revealing a card a player must give all opponents ample time to observe the revealed card before
performing additional actions. Revealing a card does not change its location, just its visibility.
All reveal abilities are instantaneous. A reveal ability targets the cards that are to be revealed.
Default Conditions
 At the completion of a reveal ability the card remains in its location and returns to its natural not visible state.

If you can't do a paired ability, you'd fall back to the default for Reveal which, as posted above, is to leave it in the previous location.

If your deck is protected from discard and RBD is out, the cards return to deck. I see no reason that Reveal+Set Aside wouldn't work the same.

so do i reveal them all at once or each individually?

Clarification About Creating Duplicate Unique Characters
"Players are restricted from performing optional game rules that would result in a player controlling multiple copies of the same unique character.  A card is protected from any ability that would cause that card to become a second copy of a unique character controlled by a single player.  If a player does end up controlling multiple copies of a unique character, all copies of that character except the original copy are discarded regardless of protection. Note: captured characters are not characters and thus do not affect these rules."

So I'm not sure how exactly this would work. This specifically says character, but should probably be changed to mean card.

the revealed cards are returned to deck
