'Next' is a word from English that is also used in German in certain situations. However, it is not used like a normal German adjective.
Für den nächsten Punkt klicken Sie bitte auf 'Next'.
For the next point, please click 'Next'.
In the meaning 'nächste/r/s' (next), 'next' is found almost exclusively as a label on buttons or in menus in software, apps, and websites.
Wenn du das Formular ausgefüllt hast, klicke auf den 'Next'-Button.
When you have filled out the form, click the 'Next' button.

The exclamation 'Next!' is very informal and is often perceived as rude or dismissive. You may know it, for example, from casting shows on television.

back
'zurück' and 'next' are opposites especially in apps, websites, or forms. 'zurück' leads to the previous step or back to the starting point. 'next' is an English word and on such buttons means 'weiter' (continue) or 'nächster Schritt' (next step). They can be confused because both often appear as short words on buttons. But the direction is different: 'zurück' goes backward, while 'next' goes forward to the next part.

Nach der Auswahl drücke ich auf „next“, weil ich zur nächsten Seite möchte.
After making my selection, I press 'next' because I want to go to the next page.
