A * * * at Destiny's Gate sent several emails that changed the world line. What are they?

Who stabbed Makase Hongliqi in the first email? (Okabe Rintarou Mobile)

The second D-mail, the lottery number. (Okabe Rintarou Mobile)

The third D-mail, telling my past self not to change my mobile phone, was essentially sent to FB, and IBN5 100 was at the shrine (sent by Tong Sheng Yu Meng's mobile phone).

The fourth D-mail, send more vegetables to give birth to healthy children (Qi Hua)

Article 5 D-mail, send kidnapping information to the past father (Phyllis)

The sixth email, tracking Amane Suzuha (sent by Okabe Rintarou's mobile phone)

* * * six in total.

If you have any questions, I have seen the door of Destiny Stone many times. Although I don't fully understand, I understand 99%.
