SP 2010 WebParts to migrate SP Online

Hi

Working on a migration of set of sites from SP 2010 to SP Online. I have come across with below web parts in 2010 farm which unlikely to migrate as-is (one of  the MVP's answered the 2010 web part "as-is compatibility" in a previous thread which is fine).

However, if anyone knows a compatible/look-a-like corresponding web part (s) for these in SP Online, so that we can customize using those instead re-build the functionality from scratch. Appreciate the help.
