Phaneritic: Are igneous rocks with crystals larger than 1 mm. You could describe the texture as coarse Here are some examples
Aphanitic: The name tells you about this texture a = not
Phaner = visible
These rocks have very fine small crystals

Porphyritic: igneous rocks, for a rock that has a distinct difference in the size of the crystals, with at least one group of crystals obviously larger than another group. Wikipedia

Glassy: Are like the name suggests no crystals and the texture of glass.

Vesicular: are igneous rocks with bubbles they can be mafic or felsic

Pyroclastic: is a mixture of rock fragments, pumice, and volcanic ash. The ash is very fine-grained, so only the rock fragments and pumice are identifiable. A rock with a pyroclastic texture is termed a tuff with small fragments, a volcanic breccia if the fragments are larger.
