Questions about spawning

I’m trying to make 3 objects spawn in 5 different locations randomly and I got stuck because the clones are overlapping and the random spawn doesn’t stop spawning. I want to make the spawner to spawn the clones in 5 different areas without overlapping and want the spawner to stop when all the areas are full.

Here’s my code.

public Transform[] spawnLocations;
public GameObject[] whatToSpawnClone;
int positionNumber;
int randomInt;


void Update()
{
        SpawnRandom();
}
    void SpawnRandom()
    {
        randomInt = Random.Range(0, whatToSpawnClone.Length);
        Instantiate(whatToSpawnClone[randomInt], spawnLocations[0].position, spawnLocations[0].rotation);
        if (positionNumber == 0)
        {
            Instantiate(whatToSpawnClone[randomInt], spawnLocations[0].position, spawnLocations[0].rotation);
            positionNumber = 1;
        }

        else if (positionNumber == 1)
        {
            Instantiate(whatToSpawnClone[randomInt], spawnLocations[1].position, spawnLocations[1].rotation);
            positionNumber = 2;
        }
        else if (positionNumber == 2)
        {
            Instantiate(whatToSpawnClone[randomInt], spawnLocations[2].position, spawnLocations[2].rotation);
            positionNumber = 3;
        }
        else if (positionNumber == 3)
        {
            Instantiate(whatToSpawnClone[randomInt], spawnLocations[3].position, spawnLocations[3].rotation);
            positionNumber = 4;
        }
        else if (positionNumber == 4)
        {
        Instantiate(whatToSpawnClone[randomInt], spawnLocations[4].position, spawnLocations[4].rotation);
        positionNumber = 0;
        }

    }
}

You should move it into your Start method if you only want it to run once.
Also heres an example of an alternative implementation

###Example:

    public List<Transform> Locations;
    public List<GameObject> Items;

    void Start()
    {
        foreach(var location in Locations)
        {
            InstantiateRandomObject(location);
        }
    }
    
    private Object InstantiateRandomObject(Transform location)
    {
        var index = Random.Range(0, Items.Count);
        return Object.Instantiate(Items[index], location.position, location.rotation);
    }

If the object is used, will it fill the empty area?
