Multiple raycast not working?

I have a problem. In my script i use more than 1 raycast, but it seems only the one on top works. If my code is messy please just say so. It's about a 2d game.

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.SceneManagement;

public class Walking : MonoBehaviour {

 public bool CanWalkRight = true;
 public bool CanWalkLeft = true;
 public bool CanWalkUp = true;
 public bool CanWalkDown = true;

 public int RayDistance;

 public KeyCode Right;
 public KeyCode Left;
 public KeyCode Up;
 public KeyCode Down;

 public KeyCode restart;

 public Rigidbody2D rb;

 // Use this for initialization
 void Start () {
     
 }

 // Update is called once per frame
 void Update()
 {
     if (Input.GetKeyDown(restart))
     {
         Invoke("Restart", 0.5f);
     }

     Debug.DrawRay(transform.position, Vector2.right, Color.red);

     if (Input.GetKeyDown(Right) && CanWalkRight == true)
     {
         rb.MovePosition(new Vector2(rb.position.x + 1, rb.position.y));
         rb.MoveRotation(0);
         Invoke("WalkReset", 0.01f);
     }

     if (Input.GetKeyDown(Left) && CanWalkLeft == true)
     {
         rb.MovePosition(new Vector2(rb.position.x + -1, rb.position.y));
         rb.MoveRotation(180);
         Invoke("WalkReset", 0.01f);
     }

     if (Input.GetKeyDown(Up) && CanWalkUp == true)
     {
         rb.MovePosition(new Vector2(rb.position.x, rb.position.y + 1));
         rb.MoveRotation(90);
         Invoke("WalkReset", 0.01f);
     }

     if (Input.GetKeyDown(Down) && CanWalkDown == true)
     {
         rb.MovePosition(new Vector2(rb.position.x, rb.position.y + -1));
         rb.MoveRotation(270);
         Invoke("WalkReset", 0.01f);
     }


     
     RaycastHit2D HitRight = Physics2D.Raycast(transform.position, Vector2.right, RayDistance);
     if (HitRight.collider.tag.Equals("Object"))
     {
          CanWalkRight = false;
     }

     Debug.Log("d");

     RaycastHit2D HitLeft = Physics2D.Raycast(transform.position, Vector2.left, RayDistance);
     if (HitLeft.collider.tag.Equals("Object"))
     {
         CanWalkLeft = false;
     }

     RaycastHit2D HitUp = Physics2D.Raycast(transform.position, Vector2.up, RayDistance);
     if (HitUp.collider.tag.Equals("Object"))
     {
         CanWalkUp = false;
     }

     RaycastHit2D HitDown = Physics2D.Raycast(transform.position, Vector2.down, RayDistance);
     if (HitDown.collider.tag.Equals("Object"))
     {
         CanWalkDown = false;
     }


     Debug.DrawRay(transform.position, Vector2.right, Color.red);


 }

 private void WalkReset()
 {
     CanWalkRight = true;
     CanWalkLeft = true;
     CanWalkUp = true;
     CanWalkDown = true;
 }

 private void Restart()
 {
     SceneManager.LoadScene(SceneManager.GetActiveScene().name);
 }

}
