HOw do i add more then 2 Ranks 

The first thing you do is add more groups /chat groups add <groupname> you will get a confirmation that the group has been created.
you can then go to your BetterChat data groups file and edit it (example below)

{
    "GroupName": "Professional",
    "Priority": 8,
    "Title": {
      "Text": "[Professional]",
      "Color": "#00ffffff",
      "Size": 17,
      "Hidden": false,
      "HiddenIfNotPrimary": false
    },
    "Username": {
      "Color": "#00ffffff",
      "Size": 17
    },
    "Message": {
      "Color": "#ffffffff",
      "Size": 17
    },
    "Format": {
      "Chat": "{Title} {Username}: {Message}",
      "Console": "{Title} {Username}: {Message}"

Then you go to the PlayerRankings CONFIG json and edit it (example below)

{
  "A": {
    "Oxide Group": "Spaz",
    "Playtime": 1.0
  },
  "B": {
    "Oxide Group": "Newbie",
    "Playtime": 5.0
  },
  "C": {
    "Oxide Group": "Noob",
    "Playtime": 15.0
  },
  "D": {
    "Oxide Group": "Learner",
    "Playtime": 50.0
  },
  "E": {
    "Oxide Group": "Provisional",
    "Playtime": 75.0
  },
  "G": {
    "Oxide Group": "Hardcase",
    "Playtime": 125.0

etc
you can as many groups as you like, i use the ranks as server rewards for kits etc by adding a permission to that group
/o.grant group <groupname> <permission name>
