Hi Nguyen Tu,
For one reference selector you can able to select only one attribute,
If you want choose Name, Color and Size in one field means you need to create another attribute in Product Entity then concat and store these 3 values in that attribute.
Then Choose the attribute in the Reference selector to display 3 values in single field
This photo is my setup
