Porphyritic texture is characterised by two distinctively different crystal sizes. Please see link.
Porphyritic
Intrusive igneous rocks commonly have large mineral crystals.

No pumice is not a porphyritic igneous rock, a porphyritic rock is characterized by the presence of phenocrysts (large mineral grains) and very small mineral grains with none in between. This implies that there was two different stages of cooling. Pumice is an extrusive igneous rock that cooled very quickly.
No. Igneous, sedimentary, and metamorphic rocks are three different categories of rock.
They are called intrusive igneous rocks, characterized by their visible mineral crystals.
there's a Latin word called "igneus" which means fire and the igneous rock is formed by lava, but that's a different subject.
