Several shaders for Geometry Normal?

How do I use multiple shaders for Geometry Normal? Do I need an additional shader for this?

You can chain multiple shaders via the normal input, like this:

You can also blend normal maps with the layer_rgba shader (see the normal map mode): https://help.autodesk.com/view/ARNOL/ENU/?guid=arnold_core_ac_layer_rgba_html

I tried to add Normal and Bump maps to layer_rgba, then connected this to Geometry Normal Standard Surface, but I still only had one map displayed. Maybe I need to adjust the blending or the type of overlay?

You can only mix the same type of maps with layer_rgba, e.g. two normal maps. Try the chain approach for different types of maps: bump connected to normal_map.normal connected to standard_surface.normal.
