One 1 cup cooked, 2.1 g protein.
Every 100 kcal of parsnips brings 1.9 g of protein. On that measure it ranks 94th of the 105 vegetables in this database and 709th of all 796 foods on the site. Measured by weight instead, its 1.32 g per 100 g ranks 68th in its group.
Only about 7% of the calories in parsnips 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 0.3 g of fat per 100 g of parsnips, too little for a protein-to-fat ratio to mean much.
Set against summer squash, another vegetable entry in the database, a serving carries about 0.5 g more protein (summer squash has 1.6 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 156 g, and it covers about 4% of the 50 g FDA Daily Value for protein.

Quick answers
1.32 g. The 1 cup cooked serving used on this page weighs 156 g and so carries 2.1 g.
1.9 g. That figure divides its 1.32 g of protein per 100 g by its 71 kcal per 100 g, so it does not depend on serving size.
No. On its own, the protein in parsnips is short of at least one essential amino acid; other protein sources across the day fill the gap.
About 4%. One 1 cup cooked serving has 2.1 g, and the FDA Daily Value for protein is 50 g.
