What does kilocalorie (IT)/hour/square foot measure?

It measures heat flux density as the rate of heat transfer of one International-Table kilocalorie per hour through one square foot of surface.

Where is Btu (th)/second/square inch commonly used?

This unit is often used in fire testing, welding experiments, and industrial furnace testing to measure intense localized heat fluxes.

Can I use these units interchangeably in all applications?

No, these units represent vastly different scales and usage contexts, so appropriate application and scale consideration are necessary.
