Yes, but only if you use :family, not :font.  You should use :family
and :height attributes.  Using :font specifies the font _and_ its
height.

Could not get tho family to be set correctly with

(buffer-face-mode-invoke
  '(:family "URW Chancery L" :height (string-to-number face-height)) t)

and

(set-face-attribute 'default nil
  :family "URW Chancery L" :height (string-to-number face-height))

The following is telling me 

Invalid face attribute :height (string-to-number face-height)

> (buffer-face-mode-invoke
> '(:family "URW Chancery L" :height (string-to-number face-height)) t)

And this does not change the family (when using "Wargames" for instance)

Maybe you use incorrect family name?  The list of available families
is produced by the function font-family-list.

I did not use that list, but the output from fc-list.

Have called (font-family-list) but the list gets truncated with "..."

("Noto Sans Bengali UI" "STIXIntegralsUp" "Noto Sans Canadian Aboriginal" 
 "Noto Sans Devanagari UI" "UnGraphic" "Noto Serif Sinhala" "Noto Sans Malayalam" 
 "Noto Serif Armenian" "Noto Sans Khmer" "Noto Sans Gurmukhi" "Junkyard" "wasy10" ...)

The "..." is the standard Emacs way of showing long lists.  Move point
there and press RET, and you will see the full list.

I used the following command in the minibuffer, but as soon as I click into
the minibuffer to press RET, the contents are removed.  

(font-family-list) C-x C-x

Have also done the following function, but the list is too 
long and gets truncated in the messages buffer.

(defun falfont-famlist ()

  (interactive)

  (dolist (font (font-family-list))

    (message "%s" font)

    (sit-for 1)))

You have quoted the whole list and so :height gets the value of
'(string-to-number face-height) rather than the result of evaluating
that as a function invocation. Go re-read the part of the textbook
that talks about basic Lisp syntax.



Possible solution:

    `(:family "URW Chancery L" :height ,(string-to-number face-height))

Use it in *scratch*, not in the minibuffer.  Then the list will not be
truncated after you press RET on the ellipsis, but will be shown
inside *scratch*, and you can scroll over it or search for the
families you want.

There should be no need for backticks and their ilk in this case.  The
values should be evaluated right away.

Yuri is likely correct because the following does work, whereas without the backtick 
and commas, it fails.

(buffer-face-mode-invoke `(:family ,face-family :height ,(string-to-number face-height)) t)

But still have got a problem with this one here

(set-face-attribute 'default nil :family face-family :height (string-to-number face-height))

Although I have executed the command in scratch, the output is printed in a new created buffer that pops up below the scratch buffer.

Evaluate the expression in *scratch* with "C-j" with point at the
right closing parenthesis.  (Sorry, I never imagined I need to explain
such basics to someone who wants to delve into fonts, families, and
faces.)
