I’m new to using the iPhone. Do all my photos remain in the camera roll?

Yes, but the Camera Roll in the Camera App and the Photos area in the Photos app are the same thing. They are not different locations.

How do I move them to the photo folder?

You don't need to move them, they are already there to begin with. You can create albums and folders and set photos to be in those albums or folders, but those are just pointers. The original photo will remain in the Library / Photos section always.

Can I make categories In the photo folder

No, you can make folders or albums. Categories such as "Videos", "Selfies", "QR codes", "Duplicates" etc.. are created automatically and dynamically curated by the system.

once they are put in the photos folder and can I remove/delete from the camera roll once they are in the photos folder folder without permanently deleting them from the photos folder?

No. All photos live in the Photos folder always. If you delete them from there they will be deleted from every folder, album or category they are in too.

The vocabulary for Photos is: Pictures can be in Albums. Albums can be in Folders. Folders don't hold individual pictures.

Some more thoughts about organization:

 In Photos, pictures aren't exactly "in" an album. When you "put a picture into an album," its name is added to a list of pictures to display together when the album is clicked, kind of like a music playlist, but for pictures. So two albums can both have the same picture name in their lists (like two playlists with the same song,)  and that picture will show up when you click either album, but there's only one picture file-- it's just on multiple lists. And when you remove a picture from an album, its name remains in the lists of other albums, and the file still remains in your Library. You don't get fewer pictures in your Library because you remove one from an album; you just get fewer names in the album list. An album is a specific list of pictures from the Photos Library-- if a picture isn't in the Photos Library, then it can't be anywhere else.

So albums give a specific view of your pictures. The picture of "Aunt Ethel at the Grand Canyon" can be in the "Aunt Ethel" album with other pictures of Aunt Ethel, and it can also be in the "Grand Canyon"  album with pictures of other people at the Grand Canyon. And it can also be in a the "September 2015" album with other things that happened then. Each album is pointing to a single file stored in the Photos Library, so having pictures in multiple albums takes up no more storage space. As you can imagine, this is very powerful in organizing pictures.

There are special views provided by Apple. The Library View is provided by Apple to give a view of all of the pictures in the entire Library in the order of their "taken" dates or their "added" dates, depending on a menu choice. If you remove a picture from the Library View, then that would be deleting it entirely. These special sections always provide the same view so that, when something goes wrong or seems off, you (and we) can depend on them always showing the same thing, and there's no chance that someone snuck in and changed the order or removed pictures. 

Recently Deleted is also just a special view of all the pictures in your Library that shows pictures you’ve marked to be erased. The names of those pictures are still on the album lists; they’re just not shown. If you “restore” a picture from Recently Deleted, then they are shown again in the albums that had listed them. Hidden is similar— the names are still in the album lists, so when you un-hide a picture it shows up again in all the albums it had been in previously.

I hope that helps…
