The Bride & Groom:
Queen Elsa & Wreck-It Ralph (of course)
Maid of Honor:
Fix-It Felix Jr. (Ralph was Felix & Tamora's Best man at their wedding, and in here it seems fair enough to return the favor)
Olaf (Though I don't know if he'll be better with the rings than Pascal & Maxims when they were Rapunzel's ring bearers
Vanellope, Taffyta, and Candlehead- I know you'll probably saying "but Taffyta & Candlehead were mean to Vanellope, why make them be fellow flower-girls with her";
Here's the thing, Taffyta & Candlehead were only mean to Vanellope when King Candy/Turbo erased their memories of her (and possibly changed their personalities).
So I'm positive that the two girls were/are friends with Venellope before and after Turbo conquered their game.
Sgt. Tamora Calhune and the modern Disney princesses (Rapunzel, Merida, and Tiana)
Horace Horsecollar (in his "Prince and the Pauper" satire)
Parents of the Bride:
*spoiler alert* Both dead
Parents of the Groom:
Any Disney & Pixar character that starred in "Disney Infinity" with the bride & groom
"The Bad Guy Meeting" group (to wish Ralph good luck)
A few video-game characters ex. Mario & Luigi (who actually showed up), Sonic the Hedgehog & Tails & Knuckles; Pikachu, and Pac-Man
