Answer 1

For example:
<VirtualHost *:80>
ServerName your_project
DocumentRoot "C:/wamp64/www/your_project"
<Directory "C:/wamp64/www/your_project/">
Options +Indexes +Includes +FollowSymLinks +MultiViews
AllowOverride All
Require local
</Directory>
</VirtualHost>

Answer 2

Let's try one more time.
Make sure all your VirtualHosts define a ServerName. Failure to do so will mean trouble as you add more hosts.
<VirtualHost *:80>
DocumentRoot /var/www/control_cuotas
ServerName control_cuotas.test
ServerAlias www.control_cuotas.test
ServerAdmin webmaster#localhost
<Directory /var/www/control_cuotas>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Require all granted
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
Don't forget to enable the above config in Apache adding it to the sites-enabled list. Then restart Apache.
The file /etc/hosts should look like this at a minimum
127.0.0.1 localhost
127.0.0.1 control_cuotas.test
127.0.0.1 www.control_cuotas.test
Other VHosts should also be represented in this file.
You can also add entries for ipV6 if you want, but it is not a requirement in most cases. (The main case is that you have disabled communication using ipV4.)
