Any tips on the best materials, design etc for a rabbit run that will consist of 5 rabbits?

Thanks

Yes, there's lots of information on this site:

But bear in mind that all the rabbits will need to be neutered or spayed (I know you've done the boys) as that usually calms the natures of both does and bucks. There'll be fighting if any of them remain entire.

In addition, when you build their accommodation, remember to construct it so that if one starts to be bullied, or is ill and needs its own space during recovery, or you need to have two groups - a three and a two - you can divide up the accommodation suitably.

Thanks,

Now im confused though....too many ideas ha

I've made some suggestions on your other thread about information you can provide to help people say what your options are.
