You can do this:
$ guile -c '(define foo 1) (load "bar.scm") (load "bif.scm")'
But I don't know how to start the REPL from Scheme code.

If your shell does process substitution, you could avoid -c, so that
guile will start the REPL as usual:
$ guile -l <(echo '(define foo 1)') -l bar.scm -l bif.scm

-e takes a *name* of an existing function, not an expression that
evaluates to a function.  It's not what you want here.  This works:
$ guile -c '(display (program-arguments)) (newline)'
(guile)

And this will print the arguments, and then start the REPL:
$ guile -e display -- args ...
(guile args ...)guile>
