Security-only updates are never cumulative on the update level, you need to install each and every one that was released. Note that they might supersede older packages on component level (inside the SXS/component store). The WUA will handle that, internally.
ESU updates are like a chain, each month's SSU enables receiving the next month's ESU patches. This might lead to the odd situation where you need to ignore the "All done" message from WOU and keep rebooting and retrying until there really isn't anything left to install.
The last thing you should get without the ESU license is the January's CU (or SecOnly+IE11 updates), the January .NET updates, and (possibly), the ESU license prep package. Additionally, you might receive further SSUs as they seem to be public (might be that they act as repair for stuck ESU licenses or packages). WU will also give you the fix for the Wallpaper handling they fudged up with the Jan packages.
Well, that's it for non-ESU machines.
