There are three basic types of firewalls that are used by companies to protect their data & devices to keep destructive elements out of network, viz. Packet Filters, Stateful Inspection and Proxy Server Firewalls. Let us give you a brief introduction about each of these.

The Windows Firewall is used to protect your Windows system from network-based threats. You can control who has access to your system and what access is granted. The Windows Firewall applet allows you to configure these firewall settings.
What's the difference between Windows Defender and Windows Firewall? Only connections which are explicitly allowed, using firewall settings, are allowed to run. Defender - It's a free antispyware program that is included windows OS. It's enabled by default.
Firewalls are software or hardware that work as a filtration system for the data attempting to enter your computer or network. Firewalls scan packets for malicious code or attack vectors that have already been identified as established threats.
Windows Firewall is a packet filter and stateful host-based firewall that allows or blocks network traffic according to the configuration.
Firewalls are essential for internet security, since they prevent anyone from the outside to access the internal network, and possibly sensitive data. However, firewalls are no panacea. In some cases, malicious hackers can still attack a vulnerable web application that is hosted behind a firewall.

Yes. If Windows Defender detects malware, it will remove it from your PC. However, because Windows doesn't update Defender's virus definitions regularly, the newest malware won't be detected, and as such, relying on Windows Defender as your sole antivirus puts your entire PC at risk of infection.
A VPN is a Virtual Private Network. The "box" or VPN device creates an encrypted tunnel between itself and a same-keyed partner device across the Internet or other insecure channel. A firewall is protection for one network from another. A firewall/VPN is simply a device which contains both of those features.
Cost for host-based firewalls is usually around $100 or less. Enterprise firewalls can cost over $25,000. The most popular medium-range business firewalls cost from $1500 to around $5000. But that's just the initial purchase price.

A firewall will not protect you from viruses and other malware. A firewall limits outside network access to a computer or local network by blocking or restricting ports. Firewalls help prevent your computer from communicating with other computers on the network and Internet.
Traditional firewall software no longer provides meaningful security, but the latest generation now offers both client-side and network protection. Firewalls have always been problematic, and today there is almost no reason to have one.” Firewalls were—and still are—no longer effective against modern attacks.
A firewall is a system designed to prevent unauthorised access to or from a private computer network. Firewalls are frequently used to prevent unauthorised Internet users from accessing private networks connected to the Internet (often described as intranets).
Firewalls can be an effective preventive measure against threats, but they shouldn't the only layer of protection. Firewalls can't protect you from email-based threats and unauthorized access to devices, for instance.
