What matches are there?

Triple H vs Roman Reigns:

Reigns earned his title shot for the World Heavyweight Championship by defeating Dean Ambrose and Brock Lesnar in a Triple Threat match at Fastlane in early March. Triple H and Reigns have been enemies for the past couple of years, but things really started to go southwards when Reigns refused Triple H's invitation to be the new face of the company.

Dean Ambrose vs Brock Lesnar:

Reigns, Ambrose and Brock faced one another at Fastlane to decide who would be the number one contender for the World Heavyweight title, and it was Reigns who emerged victorious. The next night at Raw, Brock attacked Ambrose in the parking lot as he had slammed a chair on Brock ending his goal to fight for the World Heavyweight title. After this incident, Ambrose challenged Brock for a fight, which was readily accepted by the former UFC heavyweight champion.

The Undertaker vs Shane McMahon:

The two will be colliding in a Hell in a Cell Match for ownership of Raw. Since Shane wants to run Raw, Vince McMahon has set a condition that his son has to win a match where the opponent will be of his choosing: The Undertaker. If Shane loses he no longer can demand to run Raw.
