Can anyone help identify what rank and what branch these patches and pins are from?

I was going through my grandpas old items and found these patches and pins. Can anyone please help me identify them>

Hi - 

The first item is a United States Navy rating patch.  The rank is First Class and I think it might be for a Master at Arms but I'm not sure.

The second item is a United States Air Force shoulder board for the rank of First Lieutenant.  

The third item is a United States Navy Fleet Marine Force Enlisted Warfare Speciailist insignia.  

The last two items are definitely newer pieces and I think the first one is too.

Hope this helps!
