Should i give my models a special name?

If you want it, yes.

but I think it's better for the search engine to get your models to have more generic names like "table", "male toon character", "red bottle2, etc.

Bonaldo is a brand name. If you model some uniqe table and not a copy of existing real world object, you shouldn't give it any existing brand names, as this would be misleading and also illegal. Of course, you can give some unique name to your model, but i doubt that it would make your table more appealing and it would certainly wouldn't help in search results.

for me is the best to name it as manufacturer. we will get quite offen just name of furniture, then we are loking for its 3d model
