 Geeta,
Rick is out today, so I'll try to help.
I think you are almost there. The problem is that you are setting lbFillColors to the full colormap, which has more colors than the levels that you are specifying.  So, only the first nlevels+1 colors in the color map are getting selected, which are mostly green.
Since your contours are spanning the full "precip4_11lev" colormap, you want to make sure that lbFillColors also spans the full color map. To do this, use the span_color_rgba function. Also, gsn_labelbar_ndc, by default, centers the labels under each box. However, the levels you've chosen are contour levels that represent the levels *between* each color box. For this, then, you additionally want to set lbLabelAlignment to "InteriorEdges".
Here's what your labelbar code will look like with the fixes:
  levels                  = (/5820,5840,5860,5880,5900/)
  nlevels                 = dimsizes(levels)  labels                  = "" + levels  lbres                    = True  lbres at lbAutoManage      = False  lbres at lbFillColors      = span_color_rgba ("precip_11lev",nlevels+1)  lbres at lbPerimOn           = False  lbres at lbMonoFillPattern = True  lbres at lbLabelAlignment  = "InteriorEdges"  lbres at vpWidthF          = 0.04 ; Thickness of labelbar                                                   lbres at lbLabelFontHeightF= 0.01 ; Thickness of labelbar                                                                      gsn_labelbar_ndc(wks,5,labels,0.7,0.8,lbres)

 As far as I can tell, it looks like you specify "precip_11lev" for the cnres resource, which is used in the call the gsn_csm_contour(), but then specify "CBR_wet" as the colormap used in drawing your labelbar. They are similar but not exact.

Hope that helps...
Rick

I have made 2nd label bar using gsn_labelbar_ndc function. In this label bar I have specified the fillColor as the color used for shading the contours. 
The shaded contours on the 1st Column have been used to draw the gsn_labelbar_ndc. 
but the colors are different. 
pls suggest. Geeta.
