As far a I know Gendry is the only decendant that remains of the Baratheon line. I wouldn't be surprised if we see him with a warhammer, another bull's head helment and a much better fighter; where he is now a younger version of Robert Baratheon. If he allies himself with Daenerys, she could legitimise him and therefore make him the new Lord Paramount of the Stormlands.

As for the Tyrell's, since there line isn't extinct until it's officially confirmed and we don't know if Randyll and Dickon Tarly are alive, Highgarden's occupants and the Paramount of the Reach are currently unkown.
