#1 Triple H & Stephanie McMahon vs Ronda Rousey & ???

As of this writing, this match is apparently the most likely to happen for Ronda Rousey's WWE debut match.
Ronda would get involved in a segment at WrestleMania 31 with Triple H, Stephanie McMahon and The Rock, in which the aftermath started the rumors of Rousey eventually joining WWE, or at least having a once-off match the following WrestleMania. Several sources have already confirmed that this is the match that will happen for Ronda at WrestleMania, with her male partner so far, to be confirmed.
The obvious choice would be The Rock, stemming from this segment at WrestleMania 31, and I think if Rock can make the time for it, it absolutely would happen.If not, I think the best possible replacement would be WWE RAW General Manager Kurt Angle, who has not only proved that he can still go but had been previously rumored to have a one-on-one match with Triple H in New Orleans.
