How do we repair the sides of these concrete steps?

We would like to find a way to repair the sides of the steps leading to the front entrance. The footpath area seems sturdy, but the rocks they used as filler many years ago are exposed on the sides because the concrete has fallen away. Any money saving suggestions? There’s also a walkway leading up to the steps that could use a bit of repair.
