Where do I put the Save button?

Right: 'save and exit' button next to the primary button (good). Sometimes users might need to save their progress on a long form. Putting the 'save and exit' button above the primary button implies it's more important, when it isn't.

Should save button be on top or bottom?

Considering that your users will typically navigate to one category, make a change, then click Save Changes, I think placing the button at the bottom/left is best. If your users were frequently making changes across multiple categories, then you'd have a good argument for placing the button at the top.

Should primary button be on the left or right?

Full page designs should have the primary button on the left side of the page. If the browser window is large, or you have to scroll down to fill out a form, it's best to have the primary button right below the last bit of content on the page.

What is the function of the Save button on the interface?

It's to save your progress. Normally when your in the middle of doing one of the sections you may decide to come off the computer and do something else for a while well if you hit the submit button it will save your work but also provide you with an error “if you didn't complete the section”.
