Your question is very broad and does not really provide any information. I will just assume you are asking to retrieve the names of all the user defined layer masks and answer this question:

ArrayList layerNames=new ArrayList();
for(int i=8;i<=31;i++) //user defined layers start with layer 8 and unity supports 31 layers
{
  var layerN=LayerMask.LayerToName(i); //get the name of the layer
  if(layerN.Length>0) //only add the layer if it has been named (comment this line out if you want every layer)
    layerNames.Add(layer)
}

In one line with Linq:

string[] layers = Enumerable.Range(0, 32).Select(index => LayerMask.LayerToName(index)).Where(l => !string.IsNullOrEmpty(l)).ToArray();
