Where have all the spaces gone, ...? I guess they're missing due to not using code tags.
Try

awk '{$5=sprintf("%9d", $5)} 1' file
1ABC 1111 2222 3333     12341 1001
2ABC 1111 2222 3333     12342 1002
3ABC 1111 2222 3333    112343 1003
1DEF 5555 4444 9696     12344 1004
2DEF 5555 2323 8686     12345 1005
3DEF 5555 1212 7676     12346 1006
