8 * 1/8 + 1 = 2 Fe atoms
The carbon is interstitial, in between the Fe atoms.

Kindly How many carbon atoms typically occupy interstitial sites per BCC iron unit cell in low-carbon steel?”

Yes IR, it is very different for 1012 vs 1095.
Remember that an alloy that is 1wt% C is nearly 5at% C.

Was too lazy to do the math

One BCC unit cell of ferrite contains two Fe atoms. This is what we have read in our Metallurgical Engineering classes.
My question is: this is just a theory to explain various mechanical and physical properties of metals, right? After all, the unit cell is a concept. Can it be physically verified?

of course it can be verified, X-ray diffraction does that.
And I can make macro sized single crystal samples to test and measure.

One BCC unit cell of ferrite contains one complete Fe atom and shares 1/8 of 8 Fe atoms with its neighbors.
