There are four pension papers listed, three for Elizabeth and one for Ada. I have never ordered pension papers, but would assume that each of the numbers listed apply to one, single set of documents. Therefore, you would be ordering four.
None-the-less, if you specify each by number, you should receive all four and I would assume you pay for four.
You can procure these documents through these message boards at:

No matter who you order from, you should specify you want each of the four listed by number. I would also specify the name associated with each.
My assumption is that pensions were allowed if a Certificate No. is listed.
It appears you’ve got quite a tangled mess associated with these pension applications, have you seen this?
