They are called groundwater. Far as I know, there is no specific name separating ground water in shallow water table and the ground water in confined aquifer. So you might have to called by the full description "groundwater in confined aquifer layer". Aquifer is the specifics name for porous rock and earth media in the question.
When groundwater pools between a permeable layer and an impermeable layer, an aquifer is formed. This confined aquifer can store water under pressure, creating a resource that can be tapped for drinking water and irrigation. The impermeable layer prevents water from escaping, allowing the aquifer to maintain its water levels.
Runoff and groundwater are interconnected components of the hydrological cycle. Runoff is surface water that flows over the ground and eventually recharges groundwater through infiltration. Groundwater, in turn, can discharge into surface water bodies or be pumped for various uses, completing the cycle.
Water under pressure in a confined aquifer is groundwater that is located between impermeable layers of rock or sediment and is under enough pressure that when a well is drilled into it, the water will rise above the top of the aquifer without the need for pumping. This type of aquifer is also known as an artesian aquifer.
both the water table and the groundwater is at the top of the aquifer
Groundwater can mix with runoff when surface water infiltrates into the ground and replenishes the groundwater reservoir. This mixing can occur in areas where the water table is close to the surface or in locations with permeable soils that allow for easy movement of water between surface and subsurface environments. The interaction between groundwater and runoff can impact water quality and quantity in both systems.
groundwater is dependent on the hydro-logic cycle. Water seeps to the surface and until it reaches an impermeable stratum. it then collects and can be drilled for use. If this cycle is broken the water table decreases.
"Groundwater flow is the movement of water that travels and seeps through soil and rock underground. Stored in cavities and geologic pores of the earth's crust, confined groundwater is under a great deal of pressure. Its upper part is lower than the material in which it is confined. Unconfined groundwater is the term for an aquifer with an exposed water surface."

Confined and unconfined aquifers are both underground layers of water-bearing rock or sediment. They both store and transmit groundwater. However, confined aquifers have a layer of impermeable material above them, while unconfined aquifers are closer to the surface and are not restricted by impermeable layers.
In limestone and sandstone areas, especially, ground water filtering through the rock and dissolving the limestone or sandstone, creates potholes, caverns and caves.
The precipitation stored between or within rocks is called groundwater. Groundwater is water that has infiltrated the ground and is held in the pore spaces between rocks or within the fractures of rocks. This stored water can be extracted through wells for drinking water or used to support plant life.
