Yes, cis-1,2-difluoro ethene is a polar molecule because due to cis-geometry the molecule has a net Dipole moment.
C2F2 is nonpolar because the polar bonds cancel out.
Difluoroethyne is overall nonpolar because the highly polar C-F bonds are linearly opposed and cancel each other out. The molecule would have a quadrupole moment, but I don't know the value.
It is a polar molecule and has polar bonds.
Polar
It is Polar
PBr3 is non-polar: the dipole moment of PBr3 is zero and therefor it is non-polar.

No its not polar
It is a polar molecule and has polar bonds.
Polar contains polar. Non-polar contains nothing.
