Hello,
For (1) You can use

void OnTriggerEnter(Collider col)
{
		InvokeRepeating ("MethodName", 0f, 2f);  // It will call the method "MethodName" after 0 second at every 2 seconds interval.
	}

or you can try

    void OnTriggerEnter(Collider col)
    	{
    		StartCoroutine("MethodName");
    	}

IEnumerator MethodName()
	{
		yield return new WaitForSeconds (2);
		StartCoroutine ("MethodName");
	}

You can stop these both functions calling continuously after 2 seconds by using:

  1. If you are using InvokeRepeating - CancelInvoke (“MethodName”);
  2. If you are using Coroutine - StopCoroutine(“MethodName”); or
    StopAllCoroutines (); //If there is only one coroutine in the script.
