I am using pfSense firewall, but...

I am already using pfSense firewall, but I have some questions.
1- I have recently purchased Ivacy VPN and as an addon I got NAT firewall with it.
2- Should I still be using pfSense firewall? Can I use it in addition to NAT firewall?
3- Isn't the built-in firewall of my Windows sufficient enough to protect me from any hack attacks?
4- How effective is NAT firewall? What's the difference between pfSense and NAT firewall?
I know, it's too much to ask for in a single query, but it would be really helpful if I can get any productive response in this matter.

First of, NAT determines how traffic leaving a pfSense system will be translated. Outbound NAT does not control which interface traffic will leave, only how traffic is handled as it exits. Secondly, Outbound NAT is what allows the firewall to translate your local IPs to your public one. pfSense has pre-configured rules for outbound NAT allowing you to translate your LAN networks.
"sn't the built-in firewall of my Windows sufficient enough to protect me from any hack attacks?"
I am afraid but NO!
A firewall protects you from some kinds of attacks, like worms and port scans. But a firewall does very little to protect you from viruses and other security threats, in the end you will still need a good antivirus and VPN. In practice, the most common use of NAT is to allow a private LAN to communicate with the public Internet (outbound NAT) and to allow access to servers on the private LAN from the Internet (port forwards).

Needs a VPN why exactly? Sorry but your typical user does not need a vpn..
