Various of Random Numbers?

i'm so sorry, for double posting, but my last post is a mess, and i can't get my head around it.

what i'm trying to do, is create random X position, for my spawn point, where it would instatiate a x number of enemies. i'm tryng to use Random.Range, but all it does it create one random number. all my enemies get's instantiated at that one spot each game load. how can i generate a bunch of random of random numbers so, my spawnpoint, spawns at different, positions?

i suppose i could set 3 variable, which are equal to a Random,Range, i'll try that now.

you should generate a random number each time you instantiate an enemy. like this:

for (i=0;i<5;i++){
  var rnd = Random.Range(0,10);
  Instantiate(enemy,Vector3(rnd,5,5),Quaternion.identity);
}
