How to get total list of custom settings available (if possible with the values) in Salesforce Org

Salesforce makes your custom settings into objects, so you can create a model on each custom setting sObject. I don’t know if there’s an easy way to list them.

Yah - that is true. I was trying to find if there is any easy way to get this done from Skuid. 

Looks like Metadata API and some custom Apex is the only option to go with.
