Question

did i name these correctly

Answer 1

For your first compound, you'll need to find the longest chain of carbons; which is 6. So you have hexane as your parent chain. Now, your methyl with a bromo attached to it is known as a bromomethyl and it is on the third carbon (counting left to right here). So the name of your first compound is 3-(bromomethyl)hexane.

As for your second compound, you named that correctly.
