Ray casting is a process where points of intersection with a line are computed analytically, using formulas of intersection. Ray marching is a specific algorithm, a variant on ray casting where samples are taken down a line to test for intersections or other criteria.

Path tracing is a type of ray tracing. When using path tracing for rendering, the rays only produce a single ray per bounce. The rays do not follow a defined line per bounce (to a light, for example), but rather shoot off in a random direction. The path tracing algorithm then takes a random sampling of all of the rays to create the final image.

As far as I know, all the techniques mentioned in the title are rendering algorithms that seem quite similar. All ray based techniques seem to revolve about casting rays through each pixel of an image which are supposed to represent rays of real light. This allows to render very realistic images.

Fundamentally, Raycasting involves creating a ray and calculating what it hits (or if it hits a particular thing). Raytracing involves creating a ray and tracing its path as it reflects/refracts through the scene so that you can determine what light might arrive at its source from the other direction. Very simple, non-technical explanations...

Ray tracing is more typically used to refer to the algorithm that generates the canonical rendered images using ray casting. The core component for a rendering algorithm is to evaluate how much light is coming from a specific direction at a specific point. Ray casting assumes that light only interacts at surfaces of objects.

Ray tracing produces images that can be indistinguishable from those captured by a camera. Live-action movies blend computer-generated effects and images captured in the real world seamlessly, while animated feature films cloak digitally generated scenes in light and shadow as expressive as anything shot by a cameraman.

So in ray tracing a ray is sent out from the virtual camera into the scene and traced until it intersects with a solid body. At this point a ray is cast to each of the light sources in the scene to calculate illumination and surface shading is calculated for the intersection point.
