Command `hlt-highlight-zones' from library `highlight.el'
highlights zones.  So just `C-x n a' to add each zone
and then `M-x hlt-highlight-zones'.

(`M-x hlt-unhighlight-zones' to unhighlight them.)

Or if you really want to use your `multi-region-mark-region'
then you can use `M-x zz-add-zones-from-highlighting' to
create the zones from the `multi-region-mark-region'
highlighting (assuming it uses text or overlay property
`face' or `font-lock-face').

All of this should be clear from looking at file `zones.el'.

Just set the izones variable to nil.  E.g., for the
default variable, which is `zz-izones', use this:

  M-: (setq zz-izones nil)
