Answer 1

There are a couple of useful options in SAS to do this; both create a table with all possible combinations of variables, and then you can just drop the summary data that you don't need. Given your initial dataset:

data have;
input NAME $ AMOUNT  COUNT;
datalines;
RAJ 90  1
RAVI    20  4
JOHN    30  5
JOSEPH  40  3
;;;;
run;

There is PROC FREQ with SPARSE.

proc freq data=have noprint;
tables name*amount*count/sparse out=want(drop=percent);
run;

There is also PROC TABULATE.

proc tabulate data=have out=want(keep=name amount count);
class name amount count;
tables name*amount,count /printmiss;
run;

This has the advantage of not conflicting with the name for the COUNT variable.
