I'd use 100mm for the lot, apart from the shower. If its a shower tray, it'll more than likely have a easy clean trap with a 40mm outlet. With a slab shower, loads of different methods.
Like I said before, for most your risers coming out the slab, I'd use 100mm. However, if you have an exposed concrete floor, this will become an issue because the standard 4x2 wall will probably NOT cover the pipe, leaving it for all to see. Even if the plumber is bang on to the mm, the concrete placer probably wouldn't get the best finish against the pipe (so you'd still see it). In this case you'd have to reduce it in the slab.
