Question

the literal meaning of \he names the sky his own\ is \he says the sky belongs to him\.
the figurative meaning of \he names the sky his own\ is \he is alone
he has nowhere else to go
he can go anywhere he wants\.

Explanation:

The phrase "he names the sky his own" is a metaphor. When we use metaphors, we are not using words in their literal sense. In this case, the literal meaning is that he claims the sky as his property. But the figurative meaning is more about freedom and limitless possibilities. Saying "he can go anywhere he wants" captures the idea that he has the freedom and the whole world (represented by the sky) at his disposal.

Answer:

he can go anywhere he wants
