1) Sounds like Bureaucrat is the same as Diplomat, which is already available on BGA. This card replaces the Duke. You take 2 coins and choose another player to take 1 coin.
2) We do not implement the Jester, which is another variant that replaces the Ambassador. However, the Inquisitor is already available on BGA. You can make a suggestion to add the Jester variant here:

3) Factions (teams) is already implemented on BGA as well. This divides the players into two teams, restricts players from arriving teammates, and adds actions to change teams.
