This depends on exactly how many GB the games are. This system has around 480 GB of storage, so if you add up the size of those games and it's under 480 then you're good to go!

No this computer would not be able to support that many as there are not enough ports on the graphics card. We also do not recommend using 4 monitors with this model as it can probably not keep up.

Any USB port should work for the mouse. If you continue to have issues, you can contact our customer service team and they can help you get a new one!

It is hard to compare this system to an Xbox as they run games differently. It can definitely run the games you listed, but depending on your settings they may run a bit slow since this system is very entry level.
