What is black wire in ceiling light?

The single black wire is the wire that returns from the light switch and should have a small piece of red tape on it to denote it becomes live when the light switch is turned on this wire goes into the brown of the light fitting. The two blacks do indeed go to the blue of the light as they are neutrals.

Can a neutral wire be hot?

If the neutral is disconnected anywhere between the light bulb and the panel, then the neutral from the light to the point of the break in the neutral will become hot (and the device will be unpowered, because no current will be flowing through it).

Should there be voltage on the neutral wire?

All neutral wires of the same earthed (grounded) electrical system should have the same electrical potential, because they are all connected through the system ground. Neutral conductors are usually insulated for the same voltage as the line conductors, with interesting exceptions.
