Reasonable means that whatever decision was made is appropriate given the particular circumstances, and most would regard it as so.
Justified means that whatever decision was made is done for a good reason, in the interest of fairness.
There are times the words could be used interchangeably, and contexts where the difference is subtle. It all depends on the nature of the request or issue at hand.
I might use "justified" if I was angry about something, and was acting in response:
Was it polite to skip their wedding after they insulted me like that? No, but I think my decision was justified.
I might use "reasonable" if I think everyone would agree that there was nothing else that could be done:
Was I happy about missing their wedding so that I could go to my mother's funeral? No, but I think my decision was reasonable.
But there are contexts where either word will work just fine:
You said that you'd deliver the cake before noon, but it didn't get here until 3 o'clock. I think my request for a refund is reasonable/justified.
In that sentence, reasonable would work because most people would agree that a refund would be appropriate given the circumstances, and justified would work because the request is fair.
The Oxford dictionary describes stench as:
A strong and very unpleasant smell
It describes stink as:
A strong unpleasant smell; a stench
So according to this, both words mean the same. I found also that both have the same etymology. They arise from the Old English stenc.
I was wondering if there were a shred of difference in their meanings but I am not able to find any. An English professor, very long ago, had told me that no two words in the English language have the same meaning. They may have similar meanings, but not same. But here we seem to have refuted his ideology.

"Sporting" generally means something different from "sports". I'm afraid this is another one of those cases where the expected usage of an English word can be different from its actual usage. "Sporting" is an adjective:
while "sports" is a noun:
Unfortunately the usage is mostly based on idiom. "Sports" can be used in compound nouns to mean "related to sports":
However this title could have instead used "sporting":
To complicate this, "sport" (singular) is also used in compound nouns:
Which to use ("sport", "sports", and "sporting") seems to vary between different nouns, different expressions, and even different dialects. For example, "sports country" makes sense as the name of a television or radio show:
but not in conversation (although it does seem to be used). Instead "sporting nation" seems to be used (although this may be an Indian expression):
I apologize that I'm answering your question by providing examples rather than rules, but again, the usage here seems to be based on idiom rather than grammar. It seems you might just have to repeat what you hear native speakers say.
Note: In the definition above you'll see that "sporting" has a different meaning, related to the idea of fair play in sports. If you choose to use "sporting" you have to be careful not to confuse the meanings. For example, a "sporting event" is one in which sports occur, but a "sporting gentleman" is one who believes in giving his opponent a fair chance to win -- or, in some cases, a man who likes to gamble.
