Sand
No. Limestone turns into marble, not sandstone.
When sandstone is metamorphosed it turns into Quartzite.

If broken down it turns into sandstone. If morphed it turns into gneiss.
Compaction
Sandstone turns into gneiss through a process called recrystallization, which occurs under high temperatures and pressures deep within the Earth's crust. During this process, the mineral composition and texture of the sandstone are altered, resulting in the formation of gneiss, a metamorphic rock with distinct layering and a high degree of foliation.
Clay turns into shale through compaction and cementation of fine clay particles, while sand turns into sandstone through the same process but with larger sand particles. Additionally, shale tends to have a more pronounced layering due to the smaller particle size of clay compared to sand, which results in a finer-grained texture in shale compared to sandstone.
Once burnt limestone turns into calcium oxide which is known as quicklime.
Sandstone can metamorphose into quartzite.
Pure quartz is a colorless mineral, and so a pure quartz sandstone will appear white due to multiple reflections and refractions between grains. However, impurities in the sandstone may give it some other color. What color it turns out as depends on the impurities. For example, iron oxide will produce a red sandstone.
The metamorphic process that turns sandstone into gneiss is called regional metamorphism. This process involves high temperature and pressure conditions deep within the Earth's crust, causing the minerals in the sandstone to recrystallize and align in layers to form gneiss. The distinctive banding and foliation of gneiss are a result of this intense metamorphic transformation.
