the potting seems fine so are the roots. you would probably lose that leave, but new ones will come out.
i think your plant is a bit too stressed now from all this handling and i think you overwatered a bit, its sitting already on a tray, so maybe once a week watering should be fine and let the plant rest.
the light should be fine for now, maybe you could give it some more indirect light in a few more weeks.
hope i could help you a bit and others can advice you as well.
