Will the slabs compress slightly to around 45mm

Yes, no problem. And easy to remove layers to reduce thickness to push into small cavities.

How many slabs in a pack? I need to insulate the sloping ceilings in the eaves on a dormer bungalow. 50mm will allow air circulation.

I think it was 12 slabs (that certainly fits with 6.55m in total).
