Five. Count from the first nonzero digit to the last nonzero digit.
3 of them.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
To determine the number of significant figures in the answer to the multiplication problem 532.1 x 101, you need to look at the number of significant figures in each of the numbers involved. The number 532.1 has four significant figures, while 101 has three significant figures. The final answer will have the same number of significant figures as the measurement with the least amount, which is three significant figures in this case.
If the conversion factor is exact, then the number of significant figures in the answer is the same as the number of significant figures in the original number.If the conversion factor is an approximation, then the number of significant figures in the result is the lesser of this number and the number of significant figures in the original number.
3 significant figures.

It might have been possible to answer the question if the "following" multiplication had followed. But since you did not bother to make sure that it did, I cannot provide a more useful answer.
