When is it appropriate to use "adesso" instead of "ora" when meaning "now?"

Why can't it be "lui sta fuori ora"?

I wrote "ora è fuori" and was marked wrong. Is it incorrect in Italian or should I report it ?

"Lui é ora fuori" was marked wrong. Do I really need to pay attention to the order of adverbs in Italian? In Spanish it is tottally ok to say "ahora fuera" and "fuera ahora".

Too many (appropriate) questions, but no answers whatsoever. I'd like some answers too! Guess I'll just follow the discussion

When do you use è and when do you sta? In Spanish, ser is for permanent characteristics and estar is for location or temporary conditions. But in Italian I can't find a consistency. Can anyone clarify?

i also would like to know when to use e` rather than sta

I repeat: what ever happened to stare?

I wrote : Lui è fuori ancora and got it wrong... why?

Ora è fuori wasn't accepted :/

Adesso lui è fuori. Was marked wrong. Why?
