For example, yes.

There are many other ways to write such code and the shape if the code
has no importance to `interactive`.  All that matters for `interactive`
is the *value* that is returned when the code is done running.

So you can use your above code (re-indented here, and removed the
initial value which is not helpful here (rarely is)):

    (defun myfun (type other-arg)
      (interactive
       (let ((rqmatch t) (dflt "extended") (cseq '("expression" "mixed")))
         (message "This is a message")
         (list
          (completing-read "Flare_type: " cseq nil rqmatch nil nil dflt)
          (completing-read "Other_arg: " cseq nil rqmatch nil nil dflt))))
      ...)

or

    (defun myfun (type other-arg)
      (interactive
       (list
        (let ((rqmatch t) (dflt "extended") (cseq '("expression" "mixed")) )
          (message "This is a message")
          (completing-read "Flare_type: " cseq nil rqmatch nil nil dflt))
        (let ((rqmatch t) (dflt "extended") (cseq '("expression" "mixed")) )
          (message "This is another message")
          (completing-read "Flare_type: " cseq nil rqmatch nil nil dflt))))
      ...)

or

    (defun myfun (type other-arg)
      (interactive
       (let ((rqmatch t) (dflt "extended") (cseq '("expression" "mixed")))
         (message "This is a message")
         (let ((x (completing-read "Flare_type: " cseq nil rqmatch nil nil dflt))
               (y (completing-read "Other_arg: " cseq nil rqmatch nil nil dflt)))
          `(,x ,y))))
      ...)

or

    (defun myfun (type other-arg)
      (interactive
       (let ((rqmatch t) (dflt "extended") (cseq '("expression" "mixed")))
         (message "This is a message")
         (mapcar (lambda (prompt)
                   (completing-read prompt cseq nil rqmatch nil nil dflt))
                 '("Flare_type: " "Other_arg: "))))
      ...)

or

    ...
