I ask because I work for a company and the owner has us mix all of those together (occasionally) plus a little iron micro mix and a type of conform. I feel like this is not good for the grass with all those together. Is it more effective to just do one at a time although I know that we would be spending a lot of money. Like if a grass has fungus would it be better just to spray nothing but fungicide mixed with water or is it okay to put everything in one?
Most of the time you can apply all of those types of products together and apply them at the same time so long as all the products label of the items you are using allow tank mixing. While it shouldn't harm a yard to do this, and many companies will apply multiple products together, separating the sprays even by a little can be easier on the lawn health. We would suggest using something like a fungicide by itself unless you have insect and disease damage occuring to the lawn at the same time (as in grubs, chinch bugs, etc), otherwise mix those together for applying. Then you can use a fertilizer or herbicide afterwards by a few days or even a week to not overload the lawn with chemicals.
