Congrats! They look great! You say that you don't have plans to get more but just wait
All tarantulas are venomous. Most species venom aren't that medically significant but there are a few species that, while they won't kill you, will make you very uncomfortable. It's best to avoid being bit by any species of tarantula. They can all bite but the species and the individual tarantula's attitude itself will effect the likelihood of being bit. There are no poisonous tarantulas that I know of.
