For the first one you can go to this link http://www.coscojuvenile.com/instructions/ and download the instructions, which at the end will have a parts order list, from which you can order the latch parts and the harness for the second one from there as well. you will need the model number and manufacture date on both to obtain this info and those numbers should be on the back of the seats it appears that all three are cosco car seats and you can obtain the needed parts and manuals needed.
although i will add this disclaimer, i would never never trust a car seat from a rummage sale, because you can not trust the person selling to be honest with you as to whether it was in an accident or not, if it was it may look fine, but it could have small stress fractures invisible to the human eye that could make it fail in an accident, killing or severely injuring your grandchild
also if the child is 5yrs old my better question for you would be is he over 38" tall and over 40lbs??? If so he really is to big for these car seats, you can get a booster seat for him, which would run you from 10 - 50 dollars depending on model, all of which are very safe just make sure if you do not have a head rest in the car where you will be using it, as most cars to not have these in the back seat that you get a high back booster seat (i know the first of the three list in your query works as one of these with out the harness the shoulder strap merely gets fed through the slots on the side of the seat above the child's shoulder to ensure proper alignment
if you do have the head rest you can get by with a backless one as the head rest will provide the necessary head and neck support in an accident.
with all said IF YOU DO NOT KNOW AND TRUST THE PEOPLE WHO YOU OBTAINED THESE SEATS FROM YOU CAN NOT KNOW THEY ARE REALLY SAFE AND ACCIDENT FREE
I would not stake any child's life on a used seat unless from a very very trusted source
