Is it possible that an ambiguous context free language also be a liner context free.
I have doubt regarding scope of ambiguous language in below Venn-diagram.

If I am reading your observation in the right way, I believe you are right.
It was proved by Ogden (as an application of his famous Pumping Lemma) that $\{ a^ib^jc^k \mid i=j \mbox{ or } j=k \}$ is inherently ambiguous, meaning is has no unambiguous context-free grammar. At the same time the language is linear.
Thus, in the Venn-diagram the sets "Linear CFL" and "(inherently) Ambiguous CFL" should intersect.
