Need your help with Database -phpmyadmin problems

Hi all, my developer has a few issues with my database and has requested access to my cpanel inorder to fix these problems. Though he already has login details to my database through ‘phpmyadmin’.

Can anyone help resolve these issues? Does he require access to cpanel to solve these issues?

I’ve attached to this post 4 screenshots my developer sent, detailing the issues.

Any comments, advice, help would be very much appreciated.
