ALL OF THESE ARE CORRECT

Detailed explanation-1: -If you are referring to a group of things, then all of these would be correct. If you are referring to a single thing, then all of this would be correct.
Detailed explanation-2: -This and these are used to point to something near you. For a singular thing, use this. For a plural thing, use these.
Detailed explanation-3: -If you can count the number of objects you’re talking about (like pencils, sheep, or people) use these’ or those. If you can’t count the number of objects you’re talking about (like milk, software, or rain), use this or that.
Detailed explanation-4: -"All these” means many things as part of the whole; not everything. For example I might be a boss pointing to a room full of boxes and say, “all of this needs to be moved into the next room.” I can use the word ‘this” because I mean everything. It is taken as a whole.
