These appear to be Areca palms but there are several other types of plants that look very similar. Fortunately, all of these have the same care, essentially.
It isn't necessary to split them out into their own containers, but it can help when they get crowded later. To ensure proper care, place them in a location with bright, indirect light and avoid direct sunlight. Keep the soil consistently moist but not waterlogged, and allow the top inch of soil to dry out between waterings. Maintain a temperature range of 60-75°F and high humidity. Fertilize every 2-3 months with a balanced liquid fertilizer during the growing season. Prune yellow or brown leaves as needed, and repot when the plant becomes root-bound. With proper care, your Areca palm will thrive and bring a tropical touch to your indoor space.
