The gain of an RF amplifier is the ratio of output to input power or amplitude – It is the measure of amplification of the RF amplifier.

Noise is an undesired signal that is generated up to some level in all electronics components and devices. Noise figure is the metric for noise performance is a circuit or system. The lower the noise figure, the higher the signal to noise ratio of a system.

Power Compression or P1dB is the point at which the input signal is amplified by an amount, which is 1 dB below the small signal gain of the device. It is the point beyond which the gain of the device no longer increases linearly as the input power is raised.
