A Rh negative patient cannot receive Rh positive blood as it will cause a antibody reaction to the donor plasma, but a Rh positive patient can receive Rh negative blood as the donor blood lacks the Rh antibody component.
PS the Rh factor is present on Red blood cells and not in Plasma

No, Rh negative patients should not receive Rh positive plasma as it can lead to an immune response and formation of antibodies that can cause hemolytic reactions in the future. It is important to match the Rh factor of the plasma with the Rh factor of the patient to avoid complications.
Yes, O positive can donate red blood cells to AB negative. O positive is a universal donor for red blood cells, meaning it can be transfused to individuals with any blood type. However, O positive donors are not universal plasma donors for AB negative recipients.
Just like any material, it may, or may not, be electrically neutral. What makes it a plasma is that many of its atoms are ionized - but of course the ionization process produces both positive and negative charges (the positive ions, and the electrons). If the original gas had a zero net charge, then (due to the law of conservation of charge) the resulting plasma will also have a zero net charge.
The difference between a gram positive and gram negative bacteria is the thickness/presence of the peptidoglycan layer secreted on the outside of the plasma membrane
A person who is B positive will have B antigens on their red blood cells and anti-A antibodies in their plasma. This blood type is compatible for transfusion with B positive, B negative, O positive, and O negative blood types.
The main positive electrolyte in plasma is sodium (Na+).
