The lower left one is Santa Mary. To get it, have Mary wear the Adventuring Outfit and ask her to go Explore during the Morning or Midday. Exit through the Green Barrier with her and go south; you should find a portal next to the column that says "Let maternal hands guide you." Go through and explore to find the Charm that lets you create the outfit, have her wear it, and talk to her to get the scene.
The upper right one I've explained before, but it's a random Night Elf (and an echo of Maya's - the treasure-hunter - scene). Go to the Snowy Ridge during the Morning or Midday (either by going through the blue door and making your way past the moth girls, or by using the warp crystal). North of the crystal is a weak spot in the wall; break it and go in to spy on two Night Elves scissoring. Once you've watched the (sprite) scene and listened to their dialogue, go talk to the Night Elf outside (just south of the crystal) to get the scene.
