Recent results concerning plasma instabilities and their influence on Z-pinches and liners dynamics are considered in the report. Three-dimensional two-fluid instabilities (TFI) can be responsible for the high value of anomalous electric resistance of plasma column. Two-dimensional two-fluid MHD simulation, taking into account such anomalous resistance, was performed to evaluate a threshold of sausage instability stabilization. This threshold is expressed in the terms of Z-pinch mass per unit length. Competition of the TFI's and usual Rayleigh-Taylor instability (RTI) for thin plasma liner is also discussed. The effect of an extremely fast redeployment of current from liner to a central load which had been discovered previously by the ANGARA-5 team is examined from the viewpoint of liner instabilities.
