It took me a long time to figure out how to make this. I just learned how to use Unity this year, so figure I should record things I can't find on the internet. Hopefully this helps someone else out or least give them an idea on where to start.

The code will be pasted exactly below:
________________________________

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

public class BattleCamera : MonoBehaviour
{
//transformers for objects
public Transform BattleCameraPlayerT;
public Transform BattleCameraLeftT;
public Transform BattleCameraRightT;
public Transform BattleCameraEnemyT;
public Transform BattleCameraCharacterFocusT;
public Transform MainCameraT;

//Checks button Press Amount
public int CameraMovedAmount;

//Floats
public float smoothTime;
public float rotateSpeed = 100;
public float waitTime;

//Vector3's
public Vector3 velocity = Vector3.zero;

private void Start()
{
//sets the startiing camera position to face the main player
MainCameraT.position = BattleCameraPlayerT.position;
MainCameraT.rotation = BattleCameraPlayerT.rotation;
CameraMovedAmount = 0;
}

private void Update()
{
//pressing Q moves the camera and counts how many times the button is pressed to change the angles of the camera
if (CameraMovedAmount == 0)
{
MoveCameraPlayer();
}

if (CameraMovedAmount == 1)
{
MoveCamercaRight();
}

if (CameraMovedAmount == 2)
{
MoveCameraEnemy();
}

if (CameraMovedAmount == 3)
{
MoveCameraLeft();
}

if (CameraMovedAmount == 4)
{
MoveCameraPlayerFocus();
}

if (CameraMovedAmount == 5)
{
CameraMovedAmount = 0;
}

if (Input.GetKeyDown(KeyCode.Q))
{
CameraMovedAmount += 1;
}
//This line ends the camera movement code
}

//Moves Battle Camera to the Right of the player
public void MoveCamercaRight()
{
MainCameraT.position = Vector3.SmoothDamp(MainCameraT.position, BattleCameraRightT.position, ref velocity, smoothTime);

MainCameraT.rotation = Quaternion.RotateTowards(MainCameraT.rotation, BattleCameraRightT.rotation, rotateSpeed * Time.deltaTime);
StartCoroutine(WaitForCamera());
}


//Moves Battle Camera to the right of the enemy - left of player
public void MoveCameraLeft()
{
MainCameraT.position = Vector3.SmoothDamp(MainCameraT.position, BattleCameraLeftT.position, ref velocity, smoothTime);

MainCameraT.rotation = Quaternion.RotateTowards(MainCameraT.rotation, BattleCameraLeftT.rotation, rotateSpeed * Time.deltaTime);
StartCoroutine(WaitForCamera());
}

//Moves the Battle Camera to the enemys backside view.
public void MoveCameraEnemy()
{
MainCameraT.position = Vector3.SmoothDamp(MainCameraT.position, BattleCameraEnemyT.position, ref velocity, smoothTime);

MainCameraT.rotation = Quaternion.RotateTowards(MainCameraT.rotation, BattleCameraEnemyT.rotation, rotateSpeed * Time.deltaTime);
StartCoroutine(WaitForCamera());
}

//Moves the Battle Camera to the players backside view.
public void MoveCameraPlayer()
{
MainCameraT.position = Vector3.SmoothDamp(MainCameraT.position, BattleCameraPlayerT.position, ref velocity, smoothTime);

MainCameraT.rotation = Quaternion.RotateTowards(MainCameraT.rotation, BattleCameraPlayerT.rotation, rotateSpeed * Time.deltaTime);
StartCoroutine(WaitForCamera());
}

//Moves the camera to the character/player focus position.
public void MoveCameraPlayerFocus()
{
MainCameraT.position = Vector3.SmoothDamp(MainCameraT.position, BattleCameraCharacterFocusT.position, ref velocity, smoothTime);

MainCameraT.rotation = Quaternion.RotateTowards(MainCameraT.rotation, BattleCameraCharacterFocusT.rotation, rotateSpeed * Time.deltaTime);
StartCoroutine(WaitForCamera());
}

//waits for the camera to finish moving
IEnumerator WaitForCamera()
{
yield return new WaitForSeconds(waitTime);
}
}
