how do i use get component in unity 5? the code below is just an example, it's not mine but it's similar and also doesn't work

What do you mean it doesn't work? This code should work fine. What error do you have? Do you have all Component attached in the Inspector?

the names of the scripts turn into red as soon as i type them, and i think it pops up a error, for some reason isn't showing anymore but still doesn't work

Can you please post example script so we can see what you trying to do?

 using UnityEngine;
 using System.Collections;

  public class Networking : Photon.$$anonymous$$onoBehaviour {
  FirstPersonController Char;

 void Awake() 
 {
     Char = GetComponent<FirstPersonController> ();
 }



 // Use this for initialization
 void Start () {
     PhotonNetwork.ConnectUsingSettings ("RP_v005");

     Cursor.lockState = CursorLock$$anonymous$$ode.Locked;
     Cursor.visible = (false);

     if (photonView.is$$anonymous$$ine)
     {
         Char.enabled = true;
     }
     else
     {
         enabled = true;
         Char.enabled = false;
     }

 }
 
 // Update is called once per frame
 void Update () {
     Cursor.lockState = CursorLock$$anonymous$$ode.Locked;
     Cursor.visible = (false);
 
 }

 void OnGUI() {
     GUILayout.Label (PhotonNetwork.connectionStateDetailed.ToString ());
     if (Input.Get$$anonymous$$ey($$anonymous$$eyCode.Escape))
     {
         PhotonNetwork.LoadLevel("$$anonymous$$ain$$anonymous$$enu");
     }
 }


 void OnConnectedTo$$anonymous$$aster() {
     PhotonNetwork.JoinRandomRoom ();
 }

 void OnPhotonRandomJoinFailed() {
     PhotonNetwork.CreateRoom (null);
 }

 void OnJoinedRoom() {
     GameObject myPlayerGO = (GameObject)PhotonNetwork.Instantiate ("PlayerPrefab", Vector3.zero, Quaternion.identity, 0);
     PhotonNetwork.automaticallySyncScene = true;

 }

}

And if you move the script to the StandardAssets folder? Or Try using

 using Unity.StandardAsseets

Or something like this. I'm answering from phone so can't test it at the moment.
