kindly check out indiarailinfo.com/faq/post/14 by dipyaman sir you can also search lower berth quota on google and you will get several info of the same...also to be noted is that pregnant ladies may or may not travel alone to avail this lb quota

If all are booking under a single ticket, then they will be allotted WL-56/57/58/59.
If u book single ticket for Female 62, she is guranteed a LB.
If u book another single ticket for Male 68. he is also gurantted a LB.
No special case for Kids between 5-12 as you need to book them in GN Quota itself.

do the prs clerks have the option of booking passengers in same partition, because due to high wl i book my parents via lb quota separately and every time, in different trains, on my request, the prs clerk tries and gives the berths adjacent to each other...for eg.12517 had 18 lb quota seats empty...the clerk noted down some numbers on seeing computer screen and gave two adjacent seats by booking separately under lb quota

Yes they have preference to give it in a same coach but in case 2 consecutive requests might not come in a single coach bcoz the vacancy may not exists in a single coach.
But ask the PRS Staff to provide the same coach number as of the last booked Senior Citizen.
