You can get the feature information using feature.getProperties() to get all properties or feature.get() for a specific one.

Edit: Looks like he wants to retrieve the feature info by selection. Here's OP's solution for it.

I have found solution by using ol.interaction.Select()

 var selectSingleClick = new ol.interaction.Select();
    map.addInteraction(selectSingleClick);

    map.on('singleclick', function(event){  
layerWFS.getProperties();
        layerWFS.once('precompose',function(event){
          var selectedFeatures = selectSingleClick.getFeatures();

          readFeature(selectedFeatures);

        });
    });
    function readFeature(features){

       var myfeature = features.item(0);

        console.log(myfeature.get('block_name'));
        console.log(myfeature.get('latitude'));
        console.log(myfeature.get('longitude'));
    }
