The last screenshot is for the Eternal Klash Skin Pack. The one Friendship screenshot shows Kano with a chef's at cooking sausages on the barbecue. These are goofy finishers that feature the winner doing something fun for their opponents instead of brutally killing them. One of the new features being brought back from past Mortal Kombat titles is Friendship finishers.
Another screenshot teases the return of the Dead Pool stage, a location that players will look forward to visiting in Aftermath's story. NetherRealm's teased that 'familiar foes' will threaten the future of two worlds. Who they're facing off with or why isn't clear from the screenshot. It shows Fujin standing with Nightwolf and Shang Tsung. There's one screenshot which is obviously from the new story chapter for Mortal Kombat 11.
