Connecting to MacBook Air 2017 with usb-c connection I have my work computer that I connect to my dual monitor setup, and my MacBook Air 2017 that I can't since it doesn't have a usb-c port. 

Is there any way I can use the same hub with ubc-c connection for my MacBook?
Assuming that you have a USB hub/dock with a USB-C connection....

The answer is no because the USB ports on your MBA is USB 3.0 while the USB-C connection is at minimum, 3.1.  USB is backward compatible with downstream devices and in your case, the downstream device (the hub) is a higher spec.
