Your Answer for Question 1:
c5= g4 + (p4. g3) + (p4.p3.g2) + (p4.p3.p2.g1) + (p4.p3.p2.p1.g0) + (p4.p3.p2.p1.p0.c0)


Your Answer for Question 2:
It controls the source that goes into the ALU's second input. If ALUSrc = 1 (asserted), the second ALU operand is the signed-extended, lower 16 bits of the instruction. If ALUSrc = 0 (deasserted), the second ALU operand is the second register file output (read data 2)

Your Answer for Question 3:
X = don't care, it means 0 or 1 or anything else.
o = !a + a.!c
There are four cases for the 0XX, 2 cases for 1X0, and 2 cases for the 1X1. So, there are a total of 8 different cases. Since there are 3 inputs, the number of possible input combinations is 8. Therefore, the table is complete.
