Separate Layer for each Line of Text

So your original has one text layer with four lines?

You can use a script to separate these out. These are the basic steps.

try{
    var docRef = app.activeDocument;
    var LayerRef = docRef.activeLayer;
    if(LayerRef.kind == LayerKind.TEXT){
        var LayerText = LayerRef.textItem.contents;
        LayerText = LayerText.split('\r');
        LayerRef.remove();
        for(var i = 0; i < LayerText.length; i++){
            LayerRef = docRef.artLayers.add();
            LayerRef.kind = LayerKind.TEXT;
            TextRef = LayerRef.textItem;
            TextRef.contents = LayerText[i];
            }
        }
    }
catch(e){
    Window.alert(e + ' ' + e.line);
    }
