The short answer
Split daals (masoor, moong) need 30 minutes or none. Daal channa and whole moong or masoor: 1 to 2 hours. Safaid channa and lal lobia: overnight, 8 to 10 hours.

For chickpeas and lobia, pour boiling water over them, cover and leave for an hour. It is not quite as good as overnight, but close.
