Answer 1

you do at the very beginning

using UnityEngine;

public class PlayerControler : MonoBehaviour
{
   //...
    private Animation anim;
    private void Start()
    {
        anim = GetComponent<Animator>();
        //...
    }
   //...
}

You need to change the field type from anim to Animator.
Then all other errors will disappear.
PS1: read the rules, format your questions properly
PS2: learn C# first so you don't trip over such primitive mistakes
PS3: don't shorten variable names. How much time did you save by not adding "ator" to the variable name? I think then you would intuitively understand that something is wrong with this field (why is the animator field of type Animation?)
PS4: Learn to read. In the description of all errors, it is explained in clear text what is wrong in the code. The compiler is 99% smarter than a human and just doesn't write errors.
PS5: If you can't understand the meaning of what is written, google the error code. On the MS site you can find code examples, when they occur and how to fix them.
