Unless I'm mistaken, from what I'm seeing it looks like rust bubbles in the hood hinge area of the inner fenders.

It looks like typical hood hinge area rust for an E-Body.

It's hard to see the last pic, too small and not clear enough.

If it is rust it should have been fixed, as in new metal welded in not bondo. It can have small patches welded in or you can replace the inner fenders.

As previously stated, worn hood hinges can definitely cause hood alignment problems, big time.
