1.
AC current ratios 
ac and 
ac convert directly from h parameters.
ac and ac convert directly from h parameters.2.
Besides the fact that DC = IC/IB and ac = 
IC/IB, these quantities are always the same for purposes of small-signal amplification.
DC = IC/IB and ac = IC/IB, these quantities are always the same for purposes of small-signal amplification.3.
r'e is temperature dependent.
4.
A common-collector amplifier has high input impedance, good current gain, and a voltage gain of 1.
5.
The total voltage gain of a multistage amplifier is the product of the individual stage gains.
