Could The Airborne HIV Virus + The Airborne  Ammonia Virus = Corona virus ?

1. HIV is not an airborne virus.

2. Ammonia virus is not a thing, airborne or otherwise. (Do you mean pneumonia, can be viral or bacterial)

3. Two non-existamt things cannot combine to form something.

4. Further investigation reveals the paper you refer to where it is suggested that amino acids  from HIV are in Covid-19.

5. This paper was withdrawn 2 days after its release following scathing criticism of the data used, the statistical analysis, the logic of the arguments and the conclusions reached.

Thankfully, HIV doesn't spread through the air.  You can even share a drinking glass with an HIV-infected person and not get it. (And I have!)

airborne human immunodeficiency virus would be horrible just that alone would wreck millions of lives! as of this moment that'd surpass covid-19 fairly rapidly.
