In brief: Common are trivial

We pathologists run the blood bank and are always enouraging prudent and sparing use of our product.
There's a few percent chance you'll get the sneezies and/or the itchies, a bit less that you'll get a mild fever. The very serious side effects are much less common. The one that's most worrisome is lung damage from donor antibodies -- less now that we use donors less likely to have them.

In brief: Several possibly

Reactions to blood transfusions are very rare now with the techniques that we have to "crossmatch" blood.
The most common reaction is have a rise in temperature. Next would be an allergic reaction. Most of these are not severe. The worst reaction is called a hemolytic reaction. These occur when there are important incompatibilities between your blood type and the type you have been given.

In brief: Immunologic or not

Causes for transfusion reactions may be immune related or not, also they can be acute (less than 24 hours) or delayed.
These are some: hemolytic; febrile, non-hemolytic; bacterial contamination (septic shock); anaphylaxis; transfusion-related acute lung injury (trali); transfusion-associated circulatory overload (taco); graft vs. Host disease (ta-gvhd); iron overload; infections.
