More accurately I think you mean "What type of rocks hold caves?"
The majority of caves are in Limestone; some in its metamorphic edition, Marble. These, "karst" caves, often also hold calcite deposits (stalactites etc) formed by precipitation of the calcium carbonate dissolved from the rock above the cave by the water oozing through its joints.
There are also lava tubes in basalt lava, formed by molten rock flowing from below a solidified crust.
Sea-caves and mass-movement fissures can occur in most competant rocks.
The rocks around Jenolan Caves are predominantly limestone, formed from ancient marine sedimentation. These rocks exhibit distinctive features such as cave formations due to the erosion by underground water over millions of years. Additionally, there are also dolomite and shale rocks present in the area surrounding the caves.
Karst landscape is a type of landscape where caves, deep valleys, and sinkholes are common. This type of landscape is formed by the dissolution of soluble rocks such as limestone, dolomite, or gypsum by groundwater. The result is distinctive topographical features like caves, sinkholes, and underground drainage systems.
Limestone is the type of rock that is commonly found in areas with a lot of caves. Limestone is made of calcium carbonate, which is soluble in water. Over time, as rainwater seeps into the ground, it dissolves the limestone and creates openings and caves in the rock.
This type of landscape is called a karst landscape. It is characterized by its unique geological features such as limestone caves, sinkholes, and underground streams. Karst landscapes are typically found in regions with abundant rainfall that can dissolve soluble rocks like limestone.
It's more accurate to ask what types of rock hold caves, given that a cave is a lack of rock, as i think that's what you mean! Most caves form in limestone, so the floor, walls and roof are of limestone, as are most of the boulders on the floor. Rivers can also wash in cobbles of other rock, such as Millstone grit from above the Limestone in Carboniferous formations. Lava tubes form in low-viscosity lava flows, so are in basalt or similar low-Si rock. You can also find minor caves and rock-shelters formed in other competent rocks by fluvial or sub-aeriel weathering. E,g, sea-caves, and cavities sand-blasted into sandstone rock-faces by desert sand-storms.

Caves usually and mostly forms in sedimentary rocks. Example, Limestone.
Rattlesnakes may be found under rocks and in caves. This is because the caves are dark and moist. Underneath rocks is dark and damp, too. This is the type of "climate" that rattlesnakes prefer.

Caves caused by volcanic activity are made of basalt Caves caused by dissolution due to groundwater are formed in limestone or sometimes marble. Caves also form in glacial ice due to melting. (Glacial ice can technically be considered rock.)
Sulfur is an elemental mineral, not a rock.
Sedimentary Rocks.
Kaolinite is a clay mineral belonging to the group of silicates. It is formed mainly from the weathering of rocks rich in feldspar, such as granite and gneiss. It is commonly found in sedimentary rocks and soils.
It depends on the cave. Since many caves are limestone (water carves it nicely), you usually find limestone. But granite is common in New Hampshire & Vermont.
chalk. Chalk is a type of limestone composed mainly of the mineral calcite, which is a sedimentary rock forming in marine environments. Igneous rocks are formed from the cooling and solidification of magma or lava, so chalk is not typically found in igneous rocks.
You've not given a "following" list from which to choose! Most of the world's caves are formed in limestone.
The naturally magnetic stone found in caves is called lodestone. Lodestone is a type of magnetite that has the ability to attract iron.
