Is it possible to say the two people?

The phrase "the two people" is grammatically correct, but it needs more context to be meaningful.

To make it a complete sentence, you need to add information about who these two people are or what they are doing. For example:

* "The two people walked down the street."

* "The two people at the table were arguing."

* "The two people in the photograph are my parents."

Without further context, "the two people" is just a noun phrase and doesn't express a complete thought.
