Creatures doesn't work at all. This includes animals, but excludes man (and robots)
Entities is very broad. It means the same as "Things".
You can say "intelligent beings" or some similar expression ("sentient", "self aware", "Self Perceiving"). Or even a new acronym "IBs". Since this is science fiction (no general artificial intelligence exists.) you can invent a new term for "what future people might say". Of course you need to subtlely show people what the new or changed words mean in the story. Usually you do this by using the new words with enough context for readers to understand. But now this is writing.se not ELL.
For example it might be that in the future it is considered rude to discriminate between human and artificial intelligence, so the term "people" is used for both.
There were five people on the starship. Two human and three AIs, one of whom, Katy, was embodied.
As much as they can, artificial intelligences should ensure that they are at peace with every person they relate with (whether artificial or biological), and artificial intelligences should also try to bring peace to their own environment and society.
