Jan Stránský proposed the following answer:

to 1

when you choose "GlyhpType" to "Sphere", just two lines below there is "Radius". Set it to 1 and then 
somewhat below there is "Scaling" section, set "Scale Mode" to "scalar" and "Scale Factor" to 1

> but they do not show in real radius as be in my main code.

how do you know?

> shall I set Glyph mode to All points (in Masking) for seeing spheres
in Paraview exactly with true radius in Yade?

"All points" just displays all points (paraview has some default limit on amount on shown particles).
It has NO influence on radius

> In Yade, my sphere particles are in two colour which I can distinguish
them, so in Paraview for having two colour for them: should I set
coloring to Glyphvector (in Display (Geom))?

if you use color just to distinguish two (or a few) "types" of particles, I suggest not to export color itself, but rather some "id", something like:
###
def color2scalar(color):
    if color == (1,0,0): return 1 # red
    if color == (0,0,1): return 2 # blue
    return 0 # or raise error
...exportSpheres(..., what={('color','color2scalar(b.shape.color)')})
###
then in paraview you can easily color it by the color scalar

cheers
Jan
