I took a crack at answering the original question, but I'm not surprised it got closed.
In my mind, the question has these two main problems:
1) Most words in the English language have multiple definitions (for example, property can be a piece of real estate, and feature can refer to a full-length film). Even after we remove those superfluous meanings, though, most words have multiple nuances, along with contexts where they fit well, and contexts where they sound more forced or unnatural. To break down seven synonyms, then, and try to explain where the usages overlap, and when one word is more apt than another, is a bit of a Herculean task.
2) All of these words can be looked up in various dictionaries. I'd recommend Wordnik, which not only lists meanings from multiple dictionaries, but also lists example usages, synonyms, hypernyms, and words that are used in the same context.
Put these two together, and one has to wonder: if the answer can be determined from doing some legwork at Wordnik, then why wouldn't the O.P. do that research? Alternatively, if the desire is to somehow learn more about the subtle differences between these words, then why were we given so many of them, so that the problem becomes very complicated, if not overwhelming? (A list of seven words means there are 21 pairs of words we could compare and contrast).
You say in a comment here on meta that you merely wanted "one paragraph about each word." That, too, is a hard thing to accomplish. Words like property and trait can be applied to a myriad of contexts: there are physical traits we can see, chemical traits that affect how materials react with other materials, psychological traits that determine who we are as a person and how we interact with other people, quality traits that determine if something is well-done or shoddy (those four just popped into my head – I'm sure there are more.
Lastly, if I were to describe a particular concert piece, I might describe it as fast or slow, exhilharating or haunting, trite or original, harmonious or dissonant. These are all qualities of the music piece. If we shift to a bottle of wine, the attributes change, and the qualities of the wine are something else altogether. So even a "simple paragraph for each word" is not an easy task.
My suggestion would be to do some more research on your own, and see what you can learn about these seven words, if they interest you so much. (Don't stop with the dictionary; try some searching on Google books as well.) If you find yourself curious about some apparent difference that you happen to discover but is hard to figure out, try asking that as its own question.
