Welcome to RootsChat.
Glad you found us. So many people - I think this will be too confusing to work though this all in one thread. I feel it would be best to work though each question separately. After spending 2 days studying your attachment I am still quite confused by some of it. I am sorry I don't think anybody else will be able to follow it all in one thread. I am well versed in St Columb Families and still find myself confused reading this, so I fear others will have no show of following it. There will be sections I will seek clarification on - Sections where I will disagree with your assumptions.
There is no limit to the amount of requests you can make. As we work though it please post separate topics citing what you know of each person (or family group) you are seeking help with. Rickard is a very common name in Cornwall. Some of these people connect some do not. Trying to work it all out when dozens of people have been posted alphabetically in one huge thread just wont work. Happy to help but please let us work on one section at a time.
Considering this I have left your first query re Amanda and included later mention of siblings and removed the rest.
Amanda

Elizabeth Ann (Bessy) Rickard (1852 to 1925)
Elizabeth was the sixth child of Richard James Rickard and Christian Anderson Morish. She was born on 1 August 1852, Truro, Cornwall, England although another record identifies that she was born at St. Columb Minor.
Do we have a date of christening for Elizabeth at St. Columb Minor? No I cannot find any baptisms to this couple after the move to St Col Major in either conformist or non conformist churches. She was born St Col district not Truro GRO ref St Col Sep 1/4 1852 5c 113
Charles Rickard (1863 to 1954)
Charles was the tenth I suspect he was child no 11 - the second Charles child of Richard James Rickard and Christian Anderson Morrish. He was born on 6 December 1863, This date conflicts with GRO index of Mar 1861 the first Charles and Mar 1863 the second Charles – suspect date is 6 Dec 1862 not 1863 as there is no GRO ref to substantiate this date St.Columb Major, Cornwall England and died on 25 October 1954, Box Hill, Melbourne, Victoria, Australia at the age of 90.
Was he christened at St. Columb Minor and when? No sorry no baptisms found after the move to St Columb Major
