my researchs shows me that is not possible in pschology.
in theory its still possible i think.
Not fully emotionless but some feelings like love,pain,sadness,hope...
A vegetative state might be as close as you can get to being totally emotionless without being dead.
I dont know how you would distinguish between suppressed or blocked emotional response and a natural incapability to feel a particular emotion.
If you are functioning at any concious level you have a degree of emotion because the emotion of desire is required to motivate concious movement.
I think your research couldn't have been very in-depth if you havent found any reference to a lack of ability to feel the emotions you listed.
Fear is one of the strongest emotions and fear can suppress other emotions even if we are unaware of our fear.
Just like a lot of our thinking our emotions can be unconscious
