I've seen phrases like "in the dark" and "in darkness" in many examples so far:
"I turned off the light and lay in the dark."
"All the lights went out and we were left in the dark."
"His face was in darkness."
"The lamp suddenly went out leaving us in darkness."
But can I replace "in the darkness" with "in the dark" in the following sentence?
"He was sitting alone in the darkness" (I came across this sentence in OALD).

It depends on the context. The phrase in the dark and the word darkness has several meanings. If you want to mean that phrase or words simply absence of light or illumination, both are interchangeable but then, darkness does mean the absence of moral/spiritual values or an unenlightened state.
On the other hand, in the dark also means many things and one of them is to keep someone away from the fact. For instance, Why did you keep me in the dark when you knew that she will not come for sure?
So, again, it's context based. Your sentences:
Please note that if you are using in darkness, it's an adverb as described by WW.
So I think both are interchangeable here. But be careful, you cannot replace them always. Refer this...
