Regarding what to do with the flowering stems once they've lost their flowers, I'm more on the side of "let nature do its thing". If they turn yellow and dry, cut em, else, leave em be, they might reflower on the same stem, or throw out baby plants.
If you have any more questions, send a dm :)

And put it back in its place.
An orchid losing its flowers don't mean they're dying. They might take some years to flower again, but as long as you've got leaves growing, you're doing everything right. You shouldn't see growth right now, but when flowering ends, it should start back

Doing this with the water removes chlorine, which orchids don't like. For watering, forget the tips with ice cubes and shit. I usually fill a bowl with water, let the plant sit in it until the roots turn green and plump. Remove it from bowl, put somewhere where excedent water can flow away

Next key point: no direct sunlight, but bright location. Avoid air drafts. Do not mist phalaenopsis, it leads to basal rot, and kills your plant. Try watering with rainwater or distilled water, if possible, or at least water that you put in a bottle, that you let sit for 24h in the sun,

If it's a phalaenopsis, the common ones, there's some key points. Check the base of the plant, the "soil" should only be made of bark chips. If you spot something spongy plug that resembles dirt, you should remove as much of it as possible.
