HELP- MacBook connecting multiple monitors one vertical one horizontal!

I just bought a MacBook Air and I’m switching from windows. In my current set up I have one horizontal monitor and a vertical monitor on the right side of it. I need to know how I can achieve this on Mac OS as from what I have read you can only have one external monitor. I have read about display link which I don’t understand to well? Can you connect both monitors and have one vertically. I also need help with suggestions for adapters for this with display link which ideally has more ports as the MacBook only has 2 thunderbolt ports. Are these the same as USB-C?

ANY HELP WILL BE HUGELY HELPFUL AS I NEED TO SET THIS UP FOR MY GCSE EXAM IN 2 WEEKS!!
