Changing wordpress link name

Hello

Im trying to change the name of the link of my pages. I mean i want to change the link “https://alpha-mobile-marketing.com/?page_id=175” into “https://alpha-mobile-marketing.com/page2” but this is not applicable to all pages this is only applicable to one page. I did try experimenting on the permalinks when i change the link name that was applied to all of my pages. Does anyone knows how to do this? I would really appreciate your help.

Thanks
