Change Header Font Per Page

Hello.

I would like to change the header font on a page or two on my site, but not on all pages. For example, on the link provided, I would like the page title of “Post 33⅓” to be in “built_titling” font, which I have on my desktop ready to go.
I am using the “ShopIsle” site template.

Please could someone help/advice me to do this in full?

Areas I may need to know to aid the solution include:
– how to upload the font file on the wordpress backend.
– if a wordpress plug-in is needed
– if any CSS coding is needed

Once a solution works, I would like to use the same solution to apply to another page of my site with another new font.

Many thanks for your help in advance.
Peace, Sheets.
