From a separate private discussion, here is a high level list of why each of these are wrong (on my phone so not going into too much detail)
Most play on fear or ignorance. Others are just plain factually incorrect.
1. The Mercury in vaccines is a compound that is in such small quantity it is not toxic. (Both the type of compound and quantity make it not toxic)
https://sciencebasedmedicine.org/toxic-myths-about-vaccines/2. Injecting something does not inherently make it more toxic. That's just bad science.
3. The polio vaccine cancer conspiracy is old and debunked. There was no conspiracy to hide cancer in polio vaccines. It is akin to the California law to label items that could cause cancer and ended up labeling everything.
4. There has been no findings on this, just an accusation by two people. The case was thrown out several times.
5. And 6. Factually and blatantly incorrect. Especially claiming that the Polio vaccine's impact was fabricated.
7. False. These type of studies happen all the time. Example of a major one in Japan.
https://www.medpagetoday.com/infectiousdisease/vaccines/6698. Myth. There is no 'vaccine court' superior to even the Supreme Court. Just an advisory committee of experts for civil cases.
https://www.skepticalraptor.com/skepticalraptorblog.php/vaccine-court-myths-nvicp-facts/9. Strawman that has no bearing on anything. Drug companies buy advertising just like any company. 'significant' is a matter of opinion and doesn't really mean anything.
10. Misleading. Everything contains chemicals that, depending on the dose or compound, can be toxic. Hell, water can be considered the most deadly toxin on Earth if spun wrong. This type of scare plays on plays on ignorance of how toxins work. (The toxicity is in the dose and compound).
