Hello Keshav Kumar, the four designations that you mentioned have different job profiles. But it's not like mathematics where there is a fixed and only single meaning. Across the spectrum, these terms are used loosely many a times. The airport manager is responsible for managing all personnel and operations within the airport. The aviation Manager is responsible for monitoring and ensuring compliance with the regulatory framework. Airport Programme Manager is another loosely defined term. At many airports across the world, the operator employs a programme or project manager when some new activity is undertaken. After completion of this activity, the job is terminated. The aviation Programme Manager, is in charge of planning aviation-related projects, costing, implementation, etc. I am sure that if you google, you may get much more, though confusing, information. Best wishes to you.
