What it mean as gm and Rs here?

Gm means transconductance and rs is source voltage.

Here for dc analysis we have short ckted the vdd suply so drain is grounded and automatically it is than common betn source and gate.

What mean by source follower?

Gm is slope value in any PN diode dI\dV curve called transconductance.

Gm and Rs is the voltage and source resistance.

Output Voltage is followed by input voltage so called source follower.
