Anybody can helo me with lisp routine to find lwpolylines in the drawing and mark it/these? ....
Yes, you can find them with Qselect. They are called just "Polyline" in the available Object type: choices in the Qselect pull-down list [the same as they are in the object-type slot at the top of the Properties box]. If there are any "heavy" 2D ones in the drawing, they are called "2D Polyline" in that pull-down, and if there are any 3D ones, they are called "3D Polyline."
But you can also find/select/highlight/grip them with AutoLisp, this way:
(sssetfirst nil (ssget "_X" '((0 . "LWPOLYLINE"))))

You can find them with what I suggested in Post 2, with either the AutoLisp function, or Qselect by picking Polyline in the Object type pull-down list [and don't forget Select All in the Operator pull-down list]. You can find the "heavy" ones in the same way, choosing 2D Polyline instead, or with this slightly different AutoLisp function:
(sssetfirst nil (ssget "_X" '((0 . "POLYLINE"))))
[Yes, it is confusing that "lightweight" ones are called POLYLINE in the Qselect list and the Properties box, but are called LWPOLYLINE in entity data and (ssget), while "heavy" ones are the ones called POLYLINE in entity data and (ssget), and either 2D POLYLINE or 3D POLYLINE in Qselect and Properties. They didn't design all of that very well for clarity....]
You can use the CONVERTPOLY command to change either kind [of flat ones -- not 3D] into the other kind.
