So far, your Pothos appears to be healthy. The limited brown spots can be caused by minor root damage during repotting and/or improper watering. It is not a light problem and light will not make the spots go away.
Pothos don't like having their roots disturbed and when placed in drainless pots, they are very hard to water properly because you cannot see what is happening deep in the pot where excess water may be accumulating. For future reference, it is best to leave your plants in their plastic nursery pots and set them inside a more attractive pot. That will leave the roots undisturbed and make watering much easier.
Pothos do need protection from the sun's rays falling directly on the leaves. A north window is best or off to the side of any other window.
Allow the top inch of soil to dry before adding just enough water so that the top inch dries again in about a week.
Don't fertilize more than 3 or 4 times per year and then diluted to half strength.
