the sons of the prophets

This does not mean that they were the sons of prophets, but rather, that they were a group of prophets. See how you translated this phrase in 2 Kings 2:3. Alternate translation: "the group of prophets" (See: rc://en/ta/man/jit/figs-idiom)

bowed themselves to the ground before him

They are showing him deep respect and acknowledging him as their new leader.

The spirit of Elijah does rest on Elisha

Here Elijah's "spirit" refers to his spiritual power. This speaks of Elisha having this spiritual power as if it were something that physically rested upon him. Alternate translation: "Elisha does have the same spiritual power that Elijah did" or "The spiritual power Elijah had is now with Elisha" (See: rc://en/ta/man/jit/figs-metonymy and rc://en/ta/man/jit/figs-metaphor)
