Hi
PalestineRemembered_com From within Google Earth, it is possible to set all elements the same within a folder
For example, right click on the "Gaza towns" folder and select the "style, color" tab to give you a screen shot like this
Then click the share "style button" which should give you this
Then click on the icon at the end of the "name" box to give this

and then choose an icon for all placemarks in this folder.
I've added a demo here for you to take a look at -
