difference
We use 'body' and 'one' for referring to a person like: everyone, somebody, no one etc. So I want to know is there any difference in usage between them i.e:
In other words, Is there any recommendation to choose one over another in what cases etc.
Moreover and furthermore are essentially interchangeable synonyms. They're formal substitutes for additionally, also, as well, in addition to, likewise, and too. Those two words are common in academic prose, partially because writers don't combine sentences well or often enough, partly because they need to use them to keep their sentences short enough to read without causing reader fatigue, and partly because it's the easiest way of adding additional information. I try to eliminate as many instances of moreover and furthermore as possible, but it's sometimes impossible.
In addition, they emphasize the "too-ness" of what comes next: {Moreover/Furthermore}, Judge Jones owns stock in the defendant's company, so he should recuse himself from presiding over this case.
The one you use is pretty much a question of personal taste, but my rule of thumb is to put moreover first and furthermore second if the two appear in the same paragraph on in contiguous paragraphs. Others may have a different "rule", but I think it's strictly personal choice.
Originally, cool meant someone who was somewhat standoffish in their demeanour, or someone who does not get too involved - and cold was just a more extreme form of that.
As Bill Franke points out, the meaning of cool meaning popular or trendy probably originated with cool jazz in 1945 and began being used to describe people in the 1950s seeing a rise in usage through the 1960s and a large spike in popular usage in the 1980s and 90s:
For this reason, "he's a cool guy" in modern English means "He is a trendy (or fashionable) person" rather than "His character is standoffish", whereas the meaning for cold never evolved to mean trendy, and retains its older meaning of someone who is very detached and unemotional.
If you want to use cool in the sense of someone who is slightly unemotional, you might prefer to use the idiom He's a cool cat or He's a cool character which both retain the old (non-trendy) meaning of the word cool. Alternatively you can say something like His response was somewhat cold as a less ambiguous alternative to His response was cool.

The two options are generally interchangeable. There may be some regional preferences. I believe that the -one options are considered to be slightly more formal and the -body forms slightly less formal.
As an example, here's an article from the Cambridge dictionary site specifically about "anyone" vs "anybody".
And, a general guide on indefinite pronouns that says the same:
I tend to agree with this. Some people may have other thoughts.
