orient to surface

I have this object and I have these surfaces whats the best way possible to place the object on all surfaces? and how much control can I have after ? meaning how much I can move them in the x,y,z direction ? or select some of them to alter their appearance? 

and if its a curved surface what would be the best way to place it on the surfaces ? if they are all curved? how can I compensate for the curve ? I tired surface morph but it crashes easily ?

any help would be appreciated.

Thank you
