Considering replacing all the interior doors including frames.
Existing frames are attached with long aerated concrete nails and shimmed with pieces of masonite.
That system seems a bit difficult to adjust...
it feels like regular frame screws won't grip in the aerated concrete.
There's no space to install studs for frame attachment.
Plugging and using regular long screws + shimming could be a solution...
Any tips on how to do it or how it can be done?

I used frame screws on one of the doors at home and it didn't work at all. First, I tried using dowels and screws, which ended with the dowels eventually turning (they were expensive lightweight concrete dowels) and on one of the screws, I used PL400 first so the dowel would stick, but I ended up splitting half the wall instead.
I ended up installing 11mm plywood pieces with clout nails at each frame hole for the remaining 5 doors, aligned the whole door with wedges first, and then just screwed it in, and it held well.

I suggest using Essve's Indu-Prog frame sleeve in combination with Indu-Prog lightweight concrete screw. If you want to use both suspenders and a belt, finish with foam sealant as well, and the door will be as solid as a rock for eternity.
If the wall is very porous on the surface, it might be a good idea to place a small piece of plywood (or equivalent) between the sleeve and the wall to prevent the sleeve from eating into the wall and becoming loose over time. However, this is my own idea and not something Essve recommends to my knowledge.
