Analog Circuit Help

I got fear in circuit analysis once the layout is different.
Can anyone else me how to go about solving these questions?
And from the circuit, how do we go about identify direct small signal analysis?
For 1.jpg: (a)How do i go about finding DC current from M1 - M4?
(b) What is the highest value of Vdc at gate voltage of M1 and M2?
(c) what is the DC current through M8 and the Dc voltage at output node?
(d) Find small signal gain.

For 2.jpg: How to find dc current for M4 and M5? and how to i go about finding gain?
