I only know that "よん" is means "four" (kanji: 四)

Some reference is https://en.wikipedia.org/wiki/Puyo_Puyo~n where is also "よ—ん" written.

Words and example:

うわ—い! かったよ—ん! (Source: Kingyo Chuuihou! 2 - Gyopi-chan o Sagase! - in-game conversation, after player winning one of the mini-games Wapiko conversation). Word without "よ—ん" = できたよ / with "よ—ん" = できたよ—ん ; 終わったよ = 終わったよ—ん.

    Can you add to the question? Where did you see it, who was saying it, etc.

It's nothing more than a comical or vigorous variant of the sentence-end よ. A few people use it in very informal situations. "ーん" means nothing, but is added for emphasis. It may be analogous to saying "okey-dokey" instead of "okay".
