Refridge/Freezer??????????????…

I went into the freezer last night before I went to bed and the door didn't completely close, (it was slightly open) it was open for about 15 hrs. Will the freezer be alright, and how long will it take to refreeze everything in the freezer, it has been running now for about 7 hrs and somethings still seem to be soft. Also not everything defrosted, mainly the stuff by the door witch includes ice cream, and some frozen vegetables.
