Okay, so this is only my conjecture, but... what is confusing you is the usage of the terms "Joker" and "Extra Joker" as positions within the Brave Saints organization. Each of the Brave Saints are individuals reincarnated into angels using a system based on the Evil Pieces system but using a standard playing cards as a basis. A standard deck of cards consists of 4 suits of thirteen cards (ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, jack, queen, king) and at least 1 joker card, but more usually two. The Four Great Seraphim and six lesser Seraphim (consisting of the "twins" Metatron and Sandalphon and four others) each serve in the position of "King" of a chosen suit from spades, clubs, diamonds and hearts. Based on their known choices, we can say that at least two full "decks" have probably been completed while half of a third also exists. If we assume that the cards are created in the form of full decks, then that means at least three and most likely six Joker cards exists (and that ignores any additional "decks" created in preparation for the system spraading to angels other than the Seraphim). Dulio and Lint were both reincarnated with one of these Joker cards each. However, within the organization known as Brave Saints only two official "trump card" positions: Joker and Extra Joker. The former is filled by Dulio, the latter by an as yet unnamed individual. Lint is a backup. Specifically, she is a candidate to fill the position of "Extra Joker" should it open up for some reason, be it death or something else, due to her wings' silver color (otherwise she'd be a regular "Joker" candidate, most likely).

Again, these are my conjecture based off the information we have. I'm using the ideas of multiple "decks" to push the fact that a number of Joker cards exist, not just 1 or 2, there is no guarantee that a full deck has any pertinence to the number of Joker cards, they are essentially irregularities in the syatem akin to Mutation Pieces, so the exact number of such cards to appear is uncertain, especially since we don't know how many cards in total have already been produced. The point, however, is that while the positions of Joker and Extra Joker can most likely only be filled by someone reincarnated by a Joker card, the number of such reincarnated angels is not limited to only two. There's also the possibility that she doesn't have to wait to become an official Extra Joker. She may only be regarded as a candidate due to still being considered as "in training" or some similar reason.
