When metamorphic rock melts from pressure and heat, then the product of that melt solidifies, it is considered an igneous rock.
Metamorphic rocks become igneous rocks by melting from heat and pressure, remnants of which may cool from melt (magma) and become components of igneous rock.
All rocks can become igneous rocks. With weathering and erosion, an igneous rock can become a sediment. Then with compaction and cementation, it can become a sedimentary rock. With heat and pressure, it will turn into a metamorphic rock. Or it can melt and turn into an igneous rock. There are many more ways rocks can change types... that is the rock cycle.
Two of the most common fates of igneous rocks are to become sediment (and later sedimentary rocks) or to become metamorphic rocks.
Sandstone is a sedimentary rock
Igneous rocks are a "finished product". They do not become sedimentary rock - though sedimentary rocks, with heat and pressure can become metamorphic rocks.

sedimentary rocks
no
No. Volcanic rocks are igneous (although not all igneous rocks are volcanic). Sedimentary rocks are made of sediment naturally cemented together. However, volcanic (or extrusive igneous) rocks can be eroded into sediment, which can be cemented, compacted, or otherwise become sedimentary rock such as sandstone or conglomerate. It is then not considered igneous.
