How can I delete one or some files from recycle bin?

Use right-click (or control click) and then select Delete Immediately. For multiple items you can first select the items and then right-click or control click.

Try holding down the option/alt key while trying to delete the Trash. If that doesn’t work, here is some more information.

Trash won’t empty

I may be misreading it but I think the OP is asking how to empty just one or selected files from the Trash.

I can't delete ONLY one or some files from rececle bin.

I am not sure exactly what they are trying to do - the entire Trash or just a few files.

It clearly says they want to delete a few files. Apple support are like politicians, always obfuscating things when they are caught in that zone where their software does not make sense.

Their thinking is that is you put it in the trash you must want to delete it. If I am borrowing a computer, or sharing a computer, or fixing somebody's computer and I delete a bad file, and I do not want to make a judgement call about the other party's files in the trash. It is best I delete what I added to Trash and leave the rest alone.

So apple people, answer the question.

I'm not an Apple person but I thought that I did already answer the question:

Use right-click (or control click) and then select Delete Immediately. For multiple items you can first select the items and then right-click or control click.

I just tested that again and it does allow you to "delete what I added to the Trash and leave the rest alone." Not sure it was clear that I was talking about doing that from the Trash folder but that is what I meant.
