Triumph of Courage Focus Effect: You may switch one of your focused cards with a card in your Fate discard pile. After this duel resolves, your focused cards are removed from the game instead of discarded.
Ring of Fire Focus Effect: You may give this card -2 Focus Value. If you do, and you win this duel, put this card into play.
If I focus Triumph of Courage and use its focus effect to switch Triumph with a Ring of Fire that was on my discard pile:
1) May i use Ring of fire focus effect? 2) If yes, and i win the duel may i put the ring of fire into play? Does the ring stay in play, it will be removed from the game, or it will be removed from the game then come back to play due to Ring of Fire Focus effect?

Yes, you can use Triumph of Courage to swap in Ring of Fire and use Ring of Fire's Focus Effect.
I've coved that here.
If you win the duel, Ring of Fire will be put into play. Step I of Dueling involves applying all consequences of Winning and Losing the Duel. Then Step J involves cleaning up all Focus cards - including cards in the Focus Pool and the Focused Cards Area. Since Ring of Fire isn't in the Focused Cards Area during Step J, it would not be Discarded normally, so it won't be removed from the game by Triumph of Courage "instead" either.
