Boundary Layer Meshing

Is there a way of counting the number of nodes in the boundary layer in CFD-Post?

The first photo shows the velocity contour at 90% span and the mesh around the blade.
Does it have the minimum requirement of 10 nodes in the boundary layer?
The second photo shows the distribution of y+ around the blade.
I specifed Y+=1 in turbogrid but the the distribution shows that the maximum local y plus is 5.
Do I have to refine the mesh near the boundary?
Is it correct way of inspecting Y+?
I am using SST turbulence model.
