May you change the style itself and set the same style to all layers.
You can change i.e. color of lines by "type of line" / attribute values
so you can use one style for multiple layers.

Don't know how to do that using the GUI, but for the opacity you can
use these 2 lines of python in the QGIS python console. It will set
all your selected layers to 50% opacity.
for layer in iface.layerTreeView().selectedLayers():
layer.setOpacity(.5)
I think the stroke style is harder to change because all these layers
can have different symbologies.
Hope it helps!

Hi,
I have a set of similar layers where I would like to change certain
properties for all layers in the same way.
* change opacity to 50%
* change stroke style to "no pen"
When I select multiple layers and open properties -> symbology, I
just change the styling of the first layer, not for all.
Is there a way to do this?
Regards,
Roland
