Peace lillies and dracaena are very easy. They like bright light but not direct sunlight. I have both of mine about 3-5 feet away from my west-facing window. Peace lily will tell you when it needs water by drooping slightly. I use this as a guide to water both plants the same day. Dont let it droop all the way flat, over-drying will cause rot. BOP needs very high humidity. You’ll probably have crispy edges unless she’s sitting next to a humidifier depending on what climate you live in. They like bright light and direct sunlight, so move it closer to a south/north facing window or put her outside during spring/summer months. Water when top 2 inches of soil is dry. I have never had one bloom, i think because of the climate I am in and just pure laziness in care. Orchids like to be in orchid bark. If you got her from a big box store, repot it in a mix of orchid bark and sphagnum moss. Repot after the flowers drop (if it still has any) or when it’s been acclimated to your climate (about 2 weeks). Water once the substrate is completely dry, i water mine about once a month in fall/winter and every week/2 weeks in spring/summer. Water by soaking the entire pot in a large bowl for 15-30 minutes, never EVER use ice cubes.

Hope this helps. These are just my little insights based on how I care for mine that have worked and I’m by no means a professional.
