One 1 cup, 12.3 g protein.
Every 100 kcal of fat-free refried beans brings 6.8 g of protein. On that measure it ranks 15th of the 54 legumes in this database and 362nd of all 796 foods on the site. Measured by weight instead, its 5.34 g per 100 g ranks 48th in its group.
Around 27% of the calories in fat-free refried beans come from protein, so it is moderately protein-dense. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
USDA lists 0.45 g of fat per 100 g of fat-free refried beans, too little for a protein-to-fat ratio to mean much.
Set against black-eyed peas, another legume entry in the database, a serving carries about 0.9 g less protein (black-eyed peas has 13.2 g per 1 cup cooked).
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 231 g, and it covers about 25% of the 50 g FDA Daily Value for protein.

Quick answers
5.34 g. The 1 cup serving used on this page weighs 231 g and so carries 12.3 g.
6.8 g. That figure divides its 5.34 g of protein per 100 g by its 79 kcal per 100 g, so it does not depend on serving size.
No. On its own, the protein in fat-free refried beans is short of at least one essential amino acid; other protein sources across the day fill the gap.
About 25%. One 1 cup serving has 12.3 g, and the FDA Daily Value for protein is 50 g.
