Suppose, a diode is ideal.
Q:Is it possible that the diode have finite resistance during forward bias?
Q:Is it possible that the diode have finite resistance during reversed bias?
Please explain.

yes, and yes. Diodes do NOT have infinite or zero resistance under any circumstances. Nor do any components.
But it depends on your definition of "ideal". You could define an ideal diode as having zero resistance forward and infinite resistance reverse, but that is only one definition of ideal.

I hope you mean Infinite. (finite?)
A diode will not allow any current to pass if it passes starting from it's Cathode (the dash on the diode) This would mean that you do not connect it + - + - , but + - - +. I think you might say in this matter it has infinite resistance, the thing is no matter what you do if you connect it like that no current will pass through it.
so in your circuit the current (and voltage polarity) needs to enter the diode from it's Anode side.

In electronics, a diode is a two-terminal electronic component with asymmetric transfer characteristic, with low (ideally zero) resistance to current flow in one ...This is what it means.
