I have Dark Opal basil, Lemon basil, Common sage, and Blue rosemary. Will planting any of those with/mixed in with my peppermint be a bad idea?

Since peppermint is in the mint family, it is a spreader with the likelihood of taking over surrounding plants/areas. Therefore, I would recommend planting the peppermint in a container (which can also be bottomless and sunk into the ground) to avoid this problem. As long the this plant is contained, then planting the others nearby should be ok, but I would not recommend planting them together in the same pot.
