Not sure quite what you are asking about, but anyway it is more accurate to ask what kinds of rock hold the caves, not what rocks are in the caves.
Most caves are in limestone, a sedimentary rock, irrespective of water-level. There are a few caves in igneous rock: lava-tubes in basalt-flows, but on land, not underwater. There are also a good many caves in marble, the metamorphic but still-soluble form of limestone; and again the water-level is secondary to the cave itself. A few caves exist in rock-salt, an evaporite.
Geodes are actually the result of the crystallisation of minerals in a void or cavity (also known as a vug) in a rock. They are not a type of rock themselves. They however can form in either igneous or sedimentary rocks.
Yes. Underwater caves do exist. Many formed when sea levels were lower than they are now and were flooded when sea levels rose.
Caves usually and mostly forms in sedimentary rocks. Example, Limestone.
Caves are most commonly carved out in sedimentary rocks such as limestone and kaoline. Caves are also associated with igneous rocks but mostly due to structural defects during emplacements, or adjustment due to post-orogenic activities. Nevertheles, caves can form in any rock types, and are mostly sculptured b geologic agents such as wind, running water, and waves.
Ocean caves are formed from most commonly formed by calcium and magnesium, usually sedimentary rocks. They can also be made of granite.
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.

Underwater Spelunking
Yes. Underwater caves do exist. Many formed when sea levels were lower than they are now and were flooded when sea levels rose.
Sedimentary rock
Caves usually and mostly forms in sedimentary rocks. Example, Limestone.
Because of the cascades there are a lot of igneous and metamorphic rocks. Oregon caves is a great example of metamorphic rocks. It is made from marble. I would expect mostly sedimentary and some metamorphic rocks near the ocean since it is fairly far from the cascade range. The volcanoes there are some of the most active. They are responsible for much mineralization due to heat, hydrothermal vents and lava flows. I don't know Oregon very well except the extreme southwest. You would probably do better in the geology section.
igneous rock
No life.
No, sorry there isn't.
You can't.
