Suppose in a normal Bell experiment

I assume that by electron filter you mean something like a Stern-Gerlach
apparatus that blocks one of the output beams and lets the other one through.
yes that's what I meant
Questions:
1-Would this setup produce the same result as normal Bell experiment?
No. The electrons that get through aren't entangled any more.
I was suspecting this. Then, (assuming this modified version has really
been done and result differs from normal experiment) entangled
electrons truly don't have a definite polarization.
2-If in this setup we use one electron at a time, and when A and B are
set to be oppositely oriented but not the same orientation as D and E,
would the electrons always show opposite spin?
No. You'll get the equivalent of two independent coin flips.
3-Were there really Bell experiments done with one electron at a time?
I don't know. The Aspect experiment used photons, not electrons.
