Only carbohydrate foods have a GI at all and the higher the fat, protein, and/or acidic content, the lower the GI would be . . . I honestly don't think you will find listings anywhere for those foods you mention. Suffice it to say, they likely have a relatively low GI.
HOWEVER, that alone does not make any of them a good food choice. For example, most candy bars have a pretty low GI and Cool Whip is one of the nastiest Frankenfoods around -- it is mainly HFCS and TransFat, but it definitely would not have a high GI/GL in the small amounts you should be eating.
You might want to look on a GI/GL website such as . . .
