Please show us a sample input file, the corresponding output file you are hoping to produce, and whatever awk code you have tried to use to solve this problem on your own.
I don't understand what the 4th and 5th fields in the first line of your desired output are supposed to be (nor why having mismatched parentheses in your output is desirable)???
Are the <space>s at the end of field 2 in your output present in your input file? If not, why are they present in your output file? Is your output field separator just a vertical bar character (|) or is there some reason why field 2 and field 3 in your output are separated by a variable number of <space>s and a vertical bar character? And, why are the 4th and 5th fields separated by varying numbers of <space>s instead of by vertical bar characters?

JOIN(1) General Commands Manual JOIN(1)
NAME
join - relational database operator
SYNOPSIS
join [-an] [-e s] [-o list] [-tc] file1 file2
DESCRIPTION
Join forms, on the standard output, a join of the two relations specified by the lines of file1 and file2. If file1 is `-', the standard
input is used.
File1 and file2 must be sorted in increasing ASCII collating sequence on the fields on which they are to be joined, normally the first in
each line.
There is one line in the output for each pair of lines in file1 and file2 that have identical join fields. The output line normally con-
sists of the common field, then the rest of the line from file1, then the rest of the line from file2.
Fields are normally separated by blank, tab or newline. In this case, multiple separators count as one, and leading separators are dis-
carded.
These options are recognized:
-an In addition to the normal output, produce a line for each unpairable line in file n, where n is 1 or 2.
-e s Replace empty output fields by string s.
-o list
Each output line comprises the fields specified in list, each element of which has the form n.m, where n is a file number and m is a
field number.
-tc Use character c as a separator (tab character). Every appearance of c in a line is significant.
SEE ALSO
sort(1), comm(1), awk(1).
BUGS
With default field separation, the collating sequence is that of sort -b; with -t, the sequence is that of a plain sort.
The conventions of join, sort, comm, uniq, look and awk(1) are wildly incongruous.
