error in amp

In GSC I have such error:
https://search.google.com/search-console/amp?utm_source=wmx&utm_medium=link&utm_campaign=wmx-agg&id=GzSSYGNAs1yGXgeBl-F3Ow

1. The tag ‘font’ is disallowed.
2. The tag ‘iframe’ is disallowed.
3. The tag ‘img’ may only appear as a descendant of tag ‘noscript’. Did you mean ‘amp-img’?
4. The attribute ‘action’ may not appear in tag ‘FORM [method=POST]’.
5. The attribute ‘align’ may not appear in tag ‘img’.
6. The attribute ‘clear’ may not appear in tag ‘br’.

and many others.
