Yes this has been studied and people with blood group A are more likely and more severely affected by COVID-19 compared to those with blood groups B, O, and AB.

Blood Group A has more possibility of affecting COVID-19 than other groups. There are some works of literature have identified that the A group is more prone to have affected than other blood groups.
It could be the nature of the blood characteristics but if someone has A blood group might have strong breathing practices and good immune power in the body to get rid of this virus attack.

Abstract
The novel coronavirus disease-2019 (COVID-19) has been spreading around the world rapidly and declared as a pandemic by WHO. Here, we compared the ABO blood group distribution in 2,173 patients with COVID-19 confirmed by SARS-CoV-2 test from three hospitals in Wuhan and Shenzhen, China with that in normal people from the corresponding regions. The results showed that blood group A was associated with a higher risk for acquiring COVID-19 compared with non-A blood groups, whereas blood group O was associated with a lower risk for the infection compared with non-O blood groups. This is the first observation of an association between the ABO blood type and COVID-19. It should be emphasized, however, that this is an early study with limitations. It would be premature to use this study to guide clinical practice at this time, but it should encourage further investigation of the relationship between the ABO blood group and the COVID-19 susceptibility.
Yes! Please see the link below.

People with blood type "A" have a higher risk of contracting the SARS-CoV-2 infection, while people with blood type "O" have a lower risk of contracting and developing severe COVID-19 illness.

The problem here is that many people don't know what their blood group is...😎
Yes. Some types of blood group have their specific antigens so in that case it produce resistance and increase immunity.
Yes, a recent study has indicated that people with blood group O are less prone to COVID-19 infection risk than those having blood group A. For more details, you might check it out below.

Yes, according to several restrospective study on relationship between Blood groups and COVID-19 infection-
i) Individuals with blood type O have shown lowest risk of infection of COVID-19;
ii) People with blood groups A or AB appear to exhibit greater COVID-19 disease severity than people with blood groups O or B.
