I have 3 scripts:

The first one is the manager:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class DialogueManager : MonoBehaviour

 public Text dialogueText;
 public Text nameText;
 public float sentencesSwitchDuration;
 public bool animateSentenceChars = false;
 public GameObject canvas;
 public static bool dialogueEnded = false;
 public DialogueTrigger trigger;

 private Queue<string> sentence;

 // Use this for initialization
 void Start()
 
 sentence = new Queue<string>();
 

 public void StartDialogue(Dialogue dialogue)
 
 canvas.SetActive(true);

 nameText.text = dialogue.name;

 sentence.Clear();
 foreach (string sentence in dialogue.sentences)
 
 this.sentence.Enqueue(sentence);
 

 DisplayNextSentence();
 

 public void DisplayNextSentence()
 
 if (this.sentence.Count == 0)
 
 EndDialogue();
 return;
 

 string sentence = this.sentence.Dequeue();
 dialogueText.text = sentence;

 StopAllCoroutines();
 StartCoroutine(DisplayNextSentenceWithDelay(sentence));
 

 public IEnumerator DisplayNextSentenceWithDelay(string sentence)
 
 if (animateSentenceChars)
 
 dialogueText.text = "";
 foreach (char letter in sentence.ToCharArray())
 
 dialogueText.text += letter;
 yield return null;
 
 

 yield return new WaitForSeconds(sentencesSwitchDuration);
 DisplayNextSentence();
 

 private void EndDialogue()
 
 dialogueEnded = true;
 if (trigger.dialogueNum == trigger.dialogue.Length)
 canvas.SetActive(false);
 Debug.Log("End of conversation.");
 

The second one is the trigger:

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

public class DialogueTrigger : MonoBehaviour

 public Dialogue[] dialogue;

 [HideInInspector]
 public int dialogueNum = 0;

 private bool triggered = false;
 public void TriggerDialogue()
 
 if (triggered == false)
 
 if (FindObjectOfType<DialogueManager>() != null)
 
 FindObjectOfType<DialogueManager>().StartDialogue(dialogue[dialogueNum]);
 dialogueNum += 1;
 
 triggered = true;
 
 

 private void Update()
 
 if (DialogueManager.dialogueEnded == true)
 
 if (dialogueNum == dialogue.Length)
 
 return;
 
 else
 
 FindObjectOfType<DialogueManager>().StartDialogue(dialogue[dialogueNum]);
 DialogueManager.dialogueEnded = false;
 dialogueNum += 1;
 
 
 

The last one is the dialogue:

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

[System.Serializable]
public class Dialogue

 public string name;

 [TextArea(1, 10)]
 public string[] sentences;

For example in the trigger script the array dialogue contains 3 dialogues.
The first one name is: Jhon the second Player the third Npc

The first one have 2 sentences the second have 5 sentences the last one have 1 sentence.

The problem is if in the editor I set the array of dialogues to 1 it will delete the other two. And if I will change it back to 3 it will add twice the same of the first one and will not remember the two others.

What I want to do is to add to the trigger script a global bool flag:

If true remember all the characters names and sentences if changing the dialogue array. If changing the array size higher or lower to 1 or 0 remember the characters and sentences of them.

If false don't remember the characters names and sentences if changed the dialogue array to 0 but if changed the dialogue array to 1 then remember the first one and don't remember the other two. And then if I change the dialogue array size to 3 again since the flag is false remember the first one and create two new empty dialogues.

The second problem I have is each time when I change the dialogue array size for example the size was 3 and I changed it now to 4 there is a new place in the end at the bottom. But is there a way to be able to decide to insert a new name to the chat for example in the middle of the array ? For example at the second place or third place and not always in the end ? In the editor in the inspector.

I think that what you need is to use a List instead of an array. A list will allow you to insert a new record wherever you want and also have varying lengths with no problems.
