One 1 cup, 0.9 g protein.
Every 100 kcal of grape juice brings 0.6 g of protein. On that measure it ranks 65th of the 71 fruits in this database and 790th of all 796 foods on the site. Measured by weight instead, its 0.37 g per 100 g ranks 64th in its group.
Only about 2% of the calories in grape juice come from protein, so it is more of an energy food than a protein food. It is worth eating for other reasons; the protein it adds to a day is incidental.
USDA lists 0.13 g of fat per 100 g of grape juice, too little for a protein-to-fat ratio to mean much.
Set against applesauce, another fruit entry in the database, a serving carries about 0.5 g more protein (applesauce has 0.4 g per 1 cup).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving quoted here is measured by volume at 253 g, and it covers about 2% of the 50 g FDA Daily Value for protein.

Quick answers
0.37 g. The 1 cup serving used on this page weighs 253 g and so carries 0.9 g.
0.6 g. That figure divides its 0.37 g of protein per 100 g by its 60 kcal per 100 g, so it does not depend on serving size.
No. On its own, the protein in grape juice is short of at least one essential amino acid; other protein sources across the day fill the gap.
About 2%. One 1 cup serving has 0.9 g, and the FDA Daily Value for protein is 50 g.
