Your first orchid (purple flowers, stem 8mm top / 3mm base, leaves 8cm x 1cm, small 8cm pot) has a base too thin to support the stem. Base looks dry, not green. Leaves slightly wrinkled, yellow spots. You're lost.
Sounds like a miniature orchid. Many look similar. A tag name would allow specific care.
Insert a thin (2mm) stake deep in pot, tie stem loosely—just enough to hold upright.
Reply with the tag name and I'll give exact watering, light, and repotting guidance.
