If you can't find this information online, there's a good reason for it. The military in general has become fairly restrictive when it comes to wantonly passing out names and/or contact information of service members. If this is an official request, in regards to a research topic, etc, I suggest you contact the public affairs officer for the specific units you are trying to find out about. You could always place a request with other Navy/DoD official channels, as well.
It's one thing to discuss how A4's old wingman who used to pee in the CO's coffee back in Korea is now the CO of this unit, or whatever. But it's another thing entirely to ask for all the names of all the top two Officers and CMCs for ALL the Navy's squadrons.
Just my opinion, but I really think there are better avenues to follow, especially in today's day and age.
