Did they have Cuneiform in the Paleolithic age?
Cuneiform appeared ca. 3100 BC in the Early Bronze Age with more primitive predecessors going back to perhaps ca. 4000 BC, the Paleolithic ended ca. 8000 BC.
So NO, they did not have Cuneiform in the Paleolithic age.
Use of Cuneiform overlapped the period of the end of the Neolithic age (4500 BC to 2000 BC depending on location) and the beginning of the Bronze age.
The Middle Stone Age is also called the Middle Paleolithic or Mesolithic Ages. There are two different systems of naming. One has Paleolithic and Neolithic Ages, with the Middle Stone Age being equivalent of the Middle Paleolithic Age. The other divides the Stone Age into the Old Stone Age, or Paleolithic, the Middle Stone Age or Mesolithic, and the New Stone age or Neolithic.
The Paleolithic age is old stone age about millions years ago. The Paleolithic Age is also known as the Stone Age. The Paleolithic Age, sometimes called the Stone Age, is marked by man's first use of stone tools. The lower level of that period began between 2.500,000 and 200,000 years ago. During archeological digs, some of the stone tools were found with remains, believed to be some of the first humans.
Paleolithic refers to the suffix and prefix Paleo(Ancient, Old), and Lithic(Stone). During the paleolithic era no concrete human society existed and all of humanity was nomadic. What characterizes the Paleolithic Age is the emergence of tools and nomadic tendencies among humans, before the Neolithic (Age of Civilzations), but after primitve human emergence after African Migration.
If you mean, what kind of tools did humans use in the Paleolithic age, mostly sticks (some of which were on fire), arrows & bows, and rocks chipped into arrowheads. If you mean kinds of human were living in the Paleolithic age, that depends on whether you consider other animals in our genus to be human.
