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 ALU.  If the ALUSrc signal is 1, the second ALU is the signed-extended lower 16 bits of the instruction.  If the signal is 0, the second ALU is the second register file output which is readData2.

Your Answer for Question 3:
Xs mean that we do not care about the value of the input (could be anything).

o = nota + b + c
o = a.notc + b
o = not(ac + b)= not(ac). notb = (nota + notc) .notb
  = nota.notb + notc.notb 

The table is already complete.
