3- layers / smart object / stack mode ( not active - faded color ) ) I can not proceed further.

I believe Smart Object stack modes were made unavailable in the Standard version of Photoshop CS6. The extended version unlocked some features. However, you can simulate Smart Objects and the stack modes. For instance, select all layers and set the layer blend mode to Lighten to simulate SO stack mode 'Maximum'. To fake long exposure, you'll need to manually change the Opacity of the layers. The formula is 1 divided by the layer's position in the stack. Layer 1 (bottom layer) would be 100% Opacity. Layer 2 (next layer above bottom) would be 1/2 or 50%. Layer 3: 1/3 or 33%. Layer 4: 1/4 or 25%.
