You can find many old black and white military photos at many places. One great place to find old black and white military photos is an online website. You can also find old military photos at a store like Wal-Mart or K-Mart.
If they have set their photos to a private/friends only setting then you will only be able to view them if you are friends. Some people do actually have private groups of photos where only some people are allowed to see them.

It depends on the circumstances of who took them, when. Your official photo, for example, is not protected by copyright, because it is a work of the federal government. Other photos taken by military photographers, such as are found on DVIDS, are also not protected. Snapshots, on the other hand, taken by someone whose official duties do not include photography, would be protected.
Someone can find fun photos of kittens online in many places. Reddit and Imgur will be full of fun photos of kittens. So will Cheezburger. Flickr should also have photos of kittens.
what do you call someone who develops photos
Someone can find breast reduction photos at a local Web MD US clinic. One can also find breast reduction photos on the official website of the clinic Web MD.
You can not view someone's private Instagram photos without following them.
I assume you mean photographs of yourself or family whilst serving in the military?. This is difficult and requires a lot of time posting messages on Military websites.
One can see photos of different styles of US Army helmets from Operation Helmet. One can also visit the Military Antique Museum, or one's local military museum.
Probably not, unless your great grandfather was someone famous, or he was at least somewhat well-known. We don't archive old photos, but there are some online sites that do. You may be able to find photos of the men who served in his military unit, or even find photos of places where he served. But unless there was a reason for someone to take his picture during the war, it's not something most archives would have.
