Your situation doesn't pose any risk of transmission. Below are the only risk for transmission in adults.
1. Unprotected vaginal or anal intercourse.
2. Sharing needles to inject drugs intravenously with other drug abusers.
Nothing else. No risk. Testing is not recommended.
This is very similar to your previous question. Please take note of the answer to that one and this one because it is not going to change. You can't get HIV from touching things, snorting things, etc. Air inactivates the virus. The only ways adults get HIV is from unprotected vaginal or anal sex or sharing IV drug needles. Your scenarios are on the irrational side and indicate you may have an issue with anxiety. If that is the case, that is something you can get treatment for so that you aren't afraid of impossible things. These are no risk situations you write about.
