IOS 8 using icloud Drive and sharing across 3 devices

I'm about to upgrade 3 devices for a friend
2 iphones and an ipad
I also have a windows 8 PC

i plan to use icloud drive after the update and subscribe to the space

the iphones use different appleIDs
And i would like the icloud drive i subscribe for space to be available to all the three devices - to store notes, photos etc
is this family sharing - all i can find is howto do that on icloud and NOT on icloud drive

ideally i want all the photos , notes etc to all be on the one icloud drive account and ALL available on the PC - using icloud photos - so it automatically gets a copy of any photos taken on the three devices

any advice / help please
i have looked at various youtube videos and also apple articles - But it all appears mixed with icloud and icloud drive
any clear instructions would be great

thanks

 

what about different appleIDs - which each device belongs to a different family member - how to set icloud drive - to all all to copy files to the one icloud drive and see the files on each device

 

Thanks for the replies

I was hoping the new icloud drive - would act as this common directory - so keeping with apple rather than use onedrive
is that possible with the new icloud drive as all the devices would be on ios8
or am i better using onedrive and then re directing all the camera roll etc to the one drive (which I research shows it can do)
and use that service

or have all devices on the icloud only (NOT icloud Drive) but the old icloud - so for backup and camera roll etc
and then have a common MS account to use for the Onedrive share for all devices
and have the onedrive app on all devices

friend really just wanted 1 place for all files etc
