Is this correct? Einen Elefanten? einen is singular and Elefanten is plural I think.....Can somebody clear the doubt
It is correct--Duolingo threw us kind of a mean curve ball on this one. Elefant is irregular in that it changes its ending depending on the case. There are very few nouns that work this way and unfortunately you just have to memorize them...

Are nouns that do this called "weak nouns", or am I thinking of something different?
Could you please tell me if the sentence --- It is a dog (Es ist ein Hund) is nominativ or akkusativ ............What I think is if there is a object, then it is a akkusativ, so Es ist ein Hund is correct instead of Es ist einen Hund. It is nominativ according to me.
Now why do u say, He has a elephant is akkusativ?
Very few verbs take Nominativ but sein is one of them so "Es ist ein Hund." is Nominativ.
Haben takes Akkusativ so "Sie hat einen Elefanten" is Akkusativ.
