I'm somewhat tempted to add tags for the other characters since it's pretty easy to tell who is giving what:
Kanji: The bunny
Naoto: The gift box
Chie: The chocolate covered turkey leg
Rise: The heart shaped cake (Or is that Nanako?)
Yousuke: The chocolate band-aids (those are real?)
Kuma/Teddie: The stuffed bear
Yukiko: The chocolate head that I don't recognize

The heart-shaped chocolate cake says "oniichan", so it's probably Nanako.

I assume Rise would be giving the heart in the top right corner.

As candy yes. As real bandaids that smell like chocolate, I sure hope not.

Note the cabbage leaf on the right.
