You don't need a script but a simple command (paste).
By the way, is it homework?

No Its not homework.I have the single file where I splitted into two files.For simplification I have given the above one.

cat tmp.txt

I need the output as below as single file.

awk '{a++;if(a <= 4){p[a]=$0}else{k++;print p[k]":"$0}}' file

This will work for total 8 lines of file mentioned above..Smilie

Why do you simplify your problems? Just state them as they are.
awk '{a[NR]=$0}
 print a[i],a[j++]
}' OFS=: tmp.txt

Have you checked my script?
It will handle what you require to be handled.
