It should beer fine. Just because a plant is labeled as lowlight, and does God in lowlight, doesn't mean it can't tolerate medium or even high light. There are some plants that actually can't tolerate higher lighting conditions. However, if you have taller plants or tall driftwood next to these light intolerant plants to provide shade, they should be fine. In my experience though, java fern and anubias (I assume that's what you meant by nana), can tolerate or even thrive in higher lighting conditions.
