Let's play a RAR quest?

Hello!
I brought you an easy RAR quest. The principle of the game is very simple - you need to go deeper into the archive, using data from already opened files as passwords.

So, imagine that a few hours ago, a friend of yours in IT consulting received a letter from an assistant, one Alex Lockwood, director of the secret satellite program of EDC Corporation.

Attachment .

UPD : At level 4 (a letter from the intermediary), the packaging is incorrect. If you guessed the code of Dmitry, take this archive here .
