Would tiny airborne particles be safe for our lungs ?
Would they cool earth in such a way that it would offset carbon dioxide uniformly or would it lead to even more change ? Climate change is undesirable, wether or not Climate warming is invloved.

Almost certainly not. Pretty much anything inhaled in large amounts will cause pneumoconiosis including pollen. Some stuff like asbestos or coal dust are worse than others, but even biologically inert particles tend to cause health problems.
I think that depends a lot on what density of particles is required, and how they are distributed in the atmosphere. Intuitively actually turning the whole atmosphere into something like smog would also be pretty difficult, so I would not be surprised if they could have an effect while being pretty diffuse, and that would tend to reduce the health effects, perhaps to a trivial level.
