P.S.: This is my first guide so please forgive me if something goes wrong.
 

Ending 1 (Normal Ending 2)

You can play the game as normal, but you should listen to the phone ringing.
 
 
 

Ending 2 (Let everyone in)

This ending is for everyone, regardless of who they are. Just let them all go into the building (except for the ghost). Enjoy the ending:3
 
 
 

Ending 3(You will not pa*s ending)

It doesn't matter who they are, politely decline them all and you will see.
 
 
 

Ending 4(Creepy Ending 5)

 
This ending is RNG-based, I believe. You will see the image below when you start the game from the main menu. (I got it after completing all 3 main endings,)
 
Security booth's creator stated that this ending will be activated after you have completed all three main endings. After you have completed the 3 main endings, play it again to trigger this one. Thanks Kyle 😀
 
 

 
 
If you see this, it means you are now triggering Ending 4; and once you enter the office, everything will be different from normal playthrough. You will also see the computer directly in front of your eyes.
 
Showing a game called Rite Of Pa*sage. (Cool name is not gonna be lied.)
 

 
 
Simply interact with your computer and you can start the game. You can then continue the game.
 

I won't spoil anything for you. You can play it, explore the world and enjoy the creepy ending.

 
 
 

Ending 5 (3 Pillars Ending)

 
For me, I just opened the gate once and left it open for all of the game. (I don't recommend closing the gate as it can trigger Ending 2 even if you close the gate again.)
 
 
Edit: I could be wrong. For this ending, I believe you should just let the ghost in. Then, you will trigger the ending 5.
 
 
 

Ending 6 (Car Crash ending in)

Do not stand in front of the gate, and the car will hit you. You are committing insurance fraud.
 
 
 

Ending 7 (Ultimate Super Secret ending)

You will find the gate on your right when you face the computer. This option will be available.
 
 

 
Enter the room to find the Ultimate Super Secret Ending.
 
 
 

So that's it.

I want Meeka Nomicon to thank for the endings. She made it into a short video and shared it with all of us.
 
If you are still confused or stuck on how to proceed, please check out the video she made. The video will be posted below.
 
And..thanks again for viewing my guide, which i made the first time. Also, thank you Kyle and for making this game. It was really enjoyable. Enjoy the game.
