Meaning and Definition
The initial, flexible cell wall layer deposited by a plant cell during growth.
In botany and plant biology, the first, outermost layer of a plant cell wall, composed mainly of cellulose, hemicellulose, and pectin, allowing for cell expansion. More broadly, can refer to the first or principal barrier or structure in a metaphorical sense.

No. 'Cell wall' is the general term. The 'primary wall' is specifically the first, flexible layer of that wall. Many cells later add a rigid 'secondary wall' inside the primary wall.
No. Only plant cells, fungi, bacteria, and some other organisms have cell walls. Animal cells do not have any cell wall, primary or otherwise.
Only if you are studying or writing about plant biology, botany, agriculture (specifically plant structure), or related scientific fields. It is not used in everyday conversation.
It often remains as an outer layer. In many cells, a secondary wall is then deposited on the inner side of the primary wall, providing greater strength and rigidity, sometimes causing the primary wall to become compressed.
