Rocks formed from hot molten rock that has coold and hardened are called what?
Igneous rocks.
Yes
Igneous rocks are formed by the solidification of molten materials.
Molten rock is magma. It is called lava once it has cooled and hardened.

Molten lava cooled and hardened
That is correct.
Igneous rocks
There is no such thing as an "exclusive" rock. However, there are extrusive rocks. These are divisions of igneous rocks, or rocks that form from molten rock. Intrusive rocks form from molten rock that has cooled underground. They can also be called plutonic rocks. Extrusive rocks, also called volcanic rocks, form from molten rock that has formed at or above the surface.
A rock that is formed from hardened molten rock is called an igneous rock. Igneous rocks can be formed from the cooling and solidifying of magma or lava. Examples of igneous rocks include basalt, granite, and obsidian.
They're igneous rocks, as they are formed from molten magma/ lava
