Who can talk about the pronunciation of following words: alone,

when l just listening, i fell the 'alone,  /əˈloʊn/ more like 'ə龍' , is it right?

>>>>> 

"Alone" is differ than “along”, since it has an "n" in it, rather than a ``ng’’ sound.  

Listen to their pronunciations in dictionary.com or google translate, you will see the difference.
