coarse grained and porphyry rock
Intrusive igneous rocks cool slowly. These types of rocks would be located underground having long period of time to cool.
No. Intrusive igneous rocks have large crystals because they cool slowly.
Intrusive
Quartz
Yes, rocks that cool slowly from magma have more time for crystals to grow, resulting in a coarse-grained texture with larger crystals. In contrast, rocks that cool rapidly have a fine-grained texture with smaller crystals due to the lack of time for crystal growth.

Intrusive rocks cool more slowly than extrusive rocks because they are formed beneath the Earth's surface. This slower cooling allows for larger mineral crystals to form within the rock.
Intrusive
They are surrounded by hot rock and are insulated by the surrounding material. Rocks are poor conductors of heat.

Quartz
Most do, however some do not, for instance a pseudotachylyte cools quickly.
Basalt cools off quickly because it is formed under water.
Since you have neglected to describe them or provide pictures, that cannot be determined.

Rocks cool at different rates due to how they were formed if they were formed intrusively or extrusively Examples of different igneous rocks that form differently is Granite and Gabbro form the same but different from Rhyolite.
