What do these permanently illuminated signs mean?

Your selections are correct. The green arrow above lane 1 indicates that traffic here may continue driving. The yellow arrow above lane 2 means drivers must move to the right lane soon but may still use it at this moment. The red X above lanes 3 and 4 means you are not allowed to drive in these lanes and must stop or leave them immediately. Understanding these illuminated lane signals is important, especially on highways or tunnels, as they manage traffic flow and lane safety. Always follow the lane signals to avoid fines and accidents.
