I agree with cherry. "ora" e "adesso" don't differ much and could be interchargebale in many cases but only when "ora" is used as an adverb. In fact "ora" is a noun too. In this case the meaning is different: ora - Che ora è? or - Che ore sono? What time is it ? - Ho mangiato un ora fa. I've eaten one hour ago

Adesso: It doesn't differ much from the word "ora" and is almost interchangeable: It could mean now (ora_) , just now (poco fa) or any moment now ( fra poco). - adesso non posso, sto studiando I can't do it now, I'm studying - e me lo dici adesso? now you tell me! - da adesso in poi from now on - per adesso for the moment, for now

Hello , Ora : - 'ora' could mean 'adesso' (now) .In this case you use it as in the following examples: ora sono molto occupata I'm very busy at the moment d'ora in avanti from now on It covers also a time line around the present like 'in a minute' or 'just now': -it could mean "poco fa" è uscito ora he's just gone out - It means also " tra poco" ,in a moment, in a minute ,presently: ora arrivo I'm just coming, I'll be right there - si usa in un modo correlativo : ora qui ora lì now here now there

it's absolutely the same
