Is rotational Work the same as linear Work?

Linear work is F*D and rotation is 1/2Iω², but if a problem as me rotational energy (Rotation worl = KE?) of a wheel and I have the linear work, can I just set W_rotation=W_linear?

If I have Work₁=F*D, can I use that answer to be equal to W₂(=1/2Iω²)?

Linear and rotational work can be equated, yes.

Thanks. Now is it possible to find angular momentum from just work and force? no radius, speed, nor mass are given. If so, how?

No, you need at least radius or angular speed.
