It does not get any simpler than that diagram in the wiring a ceiling rose project. The brown goes to the switched live block and the blue goes to the neutral block. I'm really sorry but if you cannot follow that it might be best if you get an electrician to do the job.
Nothing adds up. Most cables have red and black or brown and blue or even red, yellow, blue or brown, black, gray. All of these give even numbers of red and black and even if double red still does not line up with your seven wires. As we can't work this out, we are not going to give advice as we could be completely wrong. An electrician would use a meter and to try to sort this out. With information you give it can't be done safely. You really do need an electrician.
