I suggest actually reading the page you posted your comment on. (the page "buddy")

it answers your question. You can only buddy call ONCE a game, you can however choose when to buddy call and dont have to use it the first time you call a monster with the same name as your buddy. (This sometimes matters with cards that require you to be at a certain amount of life)

You can call monsters with the same name as your buddy as much as you can, but you can only perform ONE BUDDY CALL!
