Isolated footing Transfers individual column loads directly to the soil. If a single spread footing interferes with another spread footing, the two can be combined to form a combined footing.

Generally called a 'battery', as in artillery used for combined action
where there the two columns faces overlap each other, when the column face is near to the boundary line
There are some basic design principle that need to be applied when calculating the footing of a design in sandy soil. You should generally widen the footing for softer soil to allow more room for the bearing area. Since the cantilevered retaining wall is 4 foot then the footing should be 8 foot.
Combined footing is foundations supported more than one column and it’s useful when the columns are very close to each other.Usually support two columns, or three columns not in a row.Combined footings are used when tow columns are so close that single footings cannot be used or when one column is located at or near a property line.
