What does it mean? Why these special words?
They’re rhythmic and enigmatic. I can’t remember if we listened to them in Russian to hear if they sounded suitably intimidating, we must have. Because they were really melodic; I’m not sure we would have gone with them [if they weren’t]. But we wanted ones when you read them on the screen you’d have some reaction to it. Like ‘Duress,’ and ‘Freight Car.’ It’s really just us coming up with stuff. There’s not a lot of rhyme or reason to it.
On the other hand, as described in Rogue Jedi's answer, some seem not to be so random. The writers do say that that some of the words are meant to provoke a reaction.
"One," "Nine" and "Seventeen" combine to form 1917, the year Bucky was born.
Bucky "died" by falling off a freight car.
Homecoming is the name of the upcoming Spider-Man movie, but that's probably a coincidence.
These are trigger words and they are meant to be near-impossible for a non-ally to guess or say unintentionally, so at least some of the others are likely meant to be random, in-universe.

This explains why it's in Russian, instead of it being alpha-numeric ST: TNG mumbo jumbo that no one could ever possibly remember, but would be easy for a computer to hack due to its short length.
This is why a string of words would be, "near-impossible for a non-ally to guess," and why it's a good "passphrase", and why they are seemingly "random" and yet they are not.
Not based on any official source, but it would seem that they selected a collection of words that wouldn't be used in a conversational way in order to avoid false activation.
How they came upon this particular series of words, I don't know. They may have had some sort of algorithm that would generate such a "passphrase".
The words are a random assortment to prevent them from coming up in a conversation, like with "Why don't you pass the time by playing a little solitaire?"
There's another aspect that I think most people missed. Bucky responds by saying, "Ready to comply" - that last word a recurring one in various episodes of Agents of SHIELD when HYDRA brainwashing comes into play.
