I think you can, but only in cases where you have several of the same sort of item. Like say I have 20 cakes and I'm giving 6 to my friend, i might ask "Which cakes did you want?". Or say there's a pile of black coats and I'm trying to pick out my two friend's coats, i might ask "Which coats were yours again?". I'm not 100% sure if it's ~grammatically~ correct, but you definitely hear it in common language. Perhaps it's more correct to add "of these" to the sentence, EG: "Which
of these plants are weeds?" but then it's just as easy to say "Which are weeds?"

oh so confusing!
and how about
"over 18 years old" and "under 18 years old"? 18 years old belongs to both group?

More than 2 = 3 and all numbers higher than 3.
2
or more = all numbers higher than 2, INCLUDING 2
Similarly:
Less than 5 = 0,1,2, 3 or 4
5 or less =0,1,2,3,5 or 5
The "Over 18 years old" thing is trickier, because of age. 18 years and one day is technically 'over 18 years old'. So to me;
"Over 18 years old" = People who have had their 18th birthday, including people who are still 18. It's usually more clearly expressed as:
"18's and over" = 18 year olds and people aged 19 or more.
"Under 18 years old"= People who have NOT had their 18th birthday = 17 years old and younger. So 18 year olds are NOT included in this group.
Let me know if that explains things!
