Bosch Multi-Construction drills, used without hammer, will go through
fragile plaster without smashing lumps out. You can also use them with
hammer to drill bricks (although an SDS is better).

Drill a hole, maybe oversize, through the plaster. Then drill the
brick to the right size for the plugs. Use a fairly soft plug, like a
Rawl Uno. Push these deep enough into the hole that they're _entirely_
within the brick. If the plugs aren't below the plaster, then then
they expand sideways, they'll either break the plaster, or they'll
grip it so tightly that they pull it off the bricks when loaded. (One
of these seems to have happened here, but it's hard to tell which.)
Then use long enough screws to reach the deep plugs.
