This plant requires a high humidity to prosper. It needs a cool mist humidifier or set the pot on a tray filled with water and pebbles. The evaporating water will raise the humidity.
The brown edges can be caused by lack of humidity. Also, remove the leaves with the yellow spots. Apply a fungicide like Neem oil to help with the leaf spots.
I also see tiny white specs that could be dust or could be insects, such as aphids.
