Chebyshev filter with tow thomas
i've calculate the poles, but i don't know how to calculate Q and w0
  for each tow thomas.


If you have calculated the poles then this means you have calculated their position in terms of \$\sigma\$ and \$j\omega\$ and therefore you know the natural resonant frequency \$\omega_n\$ because it is the distance from the origin to each pole.

The sigma position is \$-\zeta\omega_n\$ where \$\zeta\$ = 1/2Q
