Hello João Vitor do Prado Maia,
Welcome to the MS Q&A forum.
Yes, you could deploy several VMs in the Azure Portal by sing the Deployment template.
Microsoft has the long list of all kind preconfigured templates which end user could easily use or update for their own needs.
As example, this template "VMs in Availability Zones with a Load Balancer and NAT" allows you to create 1 to 10 Virtual Machines in Availability Zones and configure NAT rules through the standard load balancer. This template also deploys a virtual network, public IP address and network interfaces.
Just click "Deploy to Azure" :)
Hope above answers your question and concern. Let me know if you need additional assistance. If the answer was helpful, please accept it and complete the quality survey so that others can find a solution.
Sincerely,
Olga Os.
