How can I manage article attachments?

First of all, just to be clear, administration is located on each article on frontend - not in Joomla! administration (backend).

Actually there are two ways how to display the attachment button.

1. You can display the button automatically in each category you select in Easy Attachments plugin configuration - "Enable In" option.
   
2. Additionally you can put the following string to your article any place you want:

   {attachments}

   
   

Who actually has an access to manage the attachments?

Each user with privileges to edit the artile.

I wanna disable ajax feature. Is that even possible?

Of course, just visit the plugin configuration and set "Ajax Layer" to "No". But my personally recommendation is leave ajax enabled.
