Does a deceased mother hear her children and know their news in her grave, and is her death in a hospital, without the exact time of death being specified, considered evidence of a bad ending, and is it permissible to cry over her?

The majority of scholars hold that the deceased can hear the speech of living visitors. As for their awareness of people's news while they are in their homes, there is no evidence for this, except what some scholars have mentioned, that they may be given glad tidings of the righteousness and obedience of their children. As for weeping, there is no harm in it if it adheres to the Shariah guidelines. What happened at the mother's death does not indicate a bad ending, and doctors should not be accused without proof.
