Does this do what you want?
RECODE Q1a Q1b Q2a (1 thru 5=1) (6 thru 99=0) (ELSE=SYSMIS) INTO X1 X2 X3.
RECODE Q18 (1=1) (2 thru 99=0) (ELSE=SYSMIS) INTO X4.
IF ANY(1,X1,X2,X3) AND (X4=0)) X5=1.
IF ((X1=0) AND (X2=0) AND (X3=0) AND (X4=1)) X5=2.
IF ANY(1,X1,X2,X3) AND (X4=1)) X5=3.
IF ((X1=0) AND (X2=0) AND (X3=0) AND (X4=0)) X5=0.
EXECUTE.
