Yes, instant yeast can be used instead of active dry yeast in these recipes. The difference between the two is that instant yeast doesn't require proofing and can be mixed directly into the flour. Instant yeast can also be added directly to the dough during the mixing stage, while active dry yeast needs to be mixed with warm water first. Use the same amount of instant yeast as active dry yeast called for in the recipe. Remember to store any unused yeast in an airtight container in the refrigerator or freezer for later use.
