I received some duck orchid seeds and am wondering what/how I can plant them? I have read that they can't be grown without their special moss. Can the moss be purchased? Is it possible to put eucalyptus oil in the soil?
The seeds must be germinated in a laboratory environment and they won't grow anywhere but in a specific environment that's only found in Australia. This is a rather technical article, but it helped me understand the problem: https://www.academia.edu/28502009/Scientific_approaches_to_terrestrial_orchid_conservation_with_particular_reference_to_Western_Australia
Also, a bit of research tells me you may not have what you think if you bought them online. Apparently these "seeds" are being sold fraudulently on the Internet. You may want to get your money back and cite these articles.

The plant appears healthy.
From your photo, I believe what you're referring to are the long aerial roots. This is normal behavior for an orchid, whose natural habitat is in the jungle, sending roots out along tree trunks for anchoring and nourishment.

Some of my orchids' leaves turned yellow. What can the reason for this be?
Most commonly, this is due to lack of fertilization. This article will help:

just trying to find out the name of this orchid and I hope it blooms
This appears to be Trizeuxis falcata. They have the same, overall, care as most orchids do. These articles will help you with orchid care:

I have 2 white orchid pot plants...............One of them flowered a second time this year. The other one has not flowered for more than 2 years. I have them indoors & keep watering them. Is there something I should be doing to get them to flower each year?
Here are a couple articles that will help:

My orchid has quite a few healthy roots that are growing and hanging over the side of the pot it is presently planted. I read that they should not be covered or they will probably not survive. Is this true? Also, what do I need to do to get my plant to produce flowers and when.
The aerial roots should not be covered or cut off. Those are the roots that help the orchid attach to trees in their native habitats. They are thicker than regular roots and silvery with a green tip. Make sure when you repot that you only cover the regular root system. Also go up about an inch in the pot size. You don't need a deeper one. And be sure to use Orchid potting mix.
To get it to rebloom, depending on the type of orchid you have, be sure to give it the recommended light, which is usually bright but indirect, do not overwater, feed it regularly with an orchid fertilizer, and increase humidity. Leaves should be a medium green with yellow overtones; that indicates they are getting enough light to rebloom.
Good luck!
