Why don't virtual hosts work in Apache?

Question

Apache HTTP Server

I set up three virtual hosts, but, for some reason, none of them work as they should.
Configurations:

https://pastebin.com/55NBH1HV

I get the following picture after going to any site:

Attached apache2.conf -- https:// pastebin.com/gKsJZXWQ
I think that there may be a problem with the rights to the folders, but I doubt it.

Answer 1

My friend, what do you have?
+ write
ServerName and ServerAlias
​​DirectoryIndex index.php index.html

Answer 2

Firstly, you need to upload the files to the DocumentRoot
And secondly, specify the DirectoryIndex parameter in the virtual hosts config
DirectoryIndex index.php index.html
