How to get each field in AWK

Input file_name:student.txt
Code:
student:      name
details of them = details_needed
class:  5th_needed
adress: address_needed

Expected output:
Code:
details of them = 5th_needed = address_needed

My code:
Code:
cat student.txt | tr '\n' '\t'| awk '{printf $5,$6,$7,$8}'

Problem:
In above code an getting only one field $5. How to get $6,$7,$8 fields??

We should use Print instead of printf.

I tired and got it.

Code:
$ cat tst
student:      name
details of them = details_needed
class:  5th_needed
adress: address_needed

Code:
$ sed '/^detail/{s/=.*//;N;N;s/\n[^:]*:/=/g;s/ *= */ = /g;p;};d' tst
details of them = 5th_needed = address_needed

Code:
$ awk -F"[\n:=]" -v RS="" '{print $3,$6,$8}' OFS="\=" tst
details of them =  5th_needed= address_needed

Code:
$ awk -F"[\n:=]" -v RS="" '{print $3,$6,$8}' OFS="\=" tst | sed 's/ *= */ = /g'
details of them = 5th_needed = address_needed
