Is it possible to get the int of a object on collision?

is it possible to get a int of a game obejct when it hits another?
//GO1 public int 1, means its player 1
//GO2 // check to see what number int is on other object to see what player attacks it?

using UnityEngine;
using System.Collections;

public class EnemyHp : MonoBehaviour {

	public static float EnemeyHp  = 5;
	public static float Hitbyplayer 0;


	//------------------------------------------------------------------------------------------------------

	void OnCollisionEnter(Col: Collision) {
		if (Col.gameObject.tag == "PlayerBullet"){
			EnemeyHp -= 1; // reduce health by 1.

	// check coliding bullet see witch player owns it. ???
			if(Hitbyplayer = 1){
				Player1Score.Player1KillsLocal += 1;
			}
			if(Hitbyplayer = 2){
				Player2Score.Player2KillsLocal += 1;
			}
			if(Hitbyplayer = 3){
				Player3Score.Player3KillsLocal += 1;
			}
			if(Hitbyplayer = 4){
				Player4Score.Player4KillsLocal += 1;
			}
			if(Hitbyplayer = 5){
				Player5Score.Player5KillsLocal += 1;
			}


				Destroy(Col.gameObject);

		}


	} // end collision check

	//------------------------------------------------------------------------------------------------------
}

For sure: just call

Col.gameObject.GetComponent<your-class-here>().your-property-here
