Answer 1

Create one Zombie scene in editor and save it. It will be saved as .tscn file. So lets call it Zombie.tscn
You can access it from code by

var zombie =   preload("res://Zombie.tscn")

and create multiple clones of it by instance()for example

for x in range(10):
        var clone = zombie.instance()
        add_child(clone)
