Metamorphic rock can be coarse grained or fine grained.
Fine grained rock exhibits a non-visible or nearly non-visible crystalline structure on a fractured surface. On the opposite end, a coarse grained rock exhibits mineral crystals of the rock's constituents on a fractured surface. The larger the crystals, the coarser grained is the rock. Basalt would be an example of a fine grained rock. Granite would be an example of a coarse grained rock.
Slate is a fine-grained, foliated, homogeneous metamorphic of silt. It is able to be cleaved into sheets which can be used as roofing slates, or left thicker to form hard wearing paths, in house building, ornamental fireplaces, and so on.
Slate is a fine-grained, foliated metamorphic rock that is created by the alteration of shale or mudstone by low-grade regional metamorphism. It is popular for a wide variety of uses such as roofing, flooring and flagging because of its durability and attractive appearance.
"Mylonite" is a term coined by Charles Lapworth in 1885 to describe a fine grained, well-laminated rock he had found in the Moine Thrust Zone of the Scottish Highlands. The term has come into general usage to indicate any foliated (and usually lineated) fine grained metamorphic rock which shows evidence for strong ductile deformation. The term is purely structural and conveys no indication of the mineralogy of the rock. Thus, a mylonite can be of any rock type.

Foliated rocks have layers in them. We often refer to the layers as Banding.

Chert is non-foliated. Foliation is a term that is used mainly to describe the appearance or texture of metamorphic rock. Chert is a sedimentary rock, composed mostly of microcrystalline quartz.

Yes. Exactly, they do have both, fine grained and coarse grained rocks.

Slate is a fine-grained, foliated, homogeneous, metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade, regional metamorphism. It is the finest-grained foliated metamorphic rock.
