This is not a set answer. All of these factors should fluctuate, slightly, throughout the year. In fact, that is how you know that the plant is performing properly! Except for sunlight, all of these factors should change some. All of these plants require full sun for as long as they can get it.
When you water, you will want to do so until water comes out of your drainage holes. Then, remove all extra water, so that it does not sit in it. Or water deeply, if in the ground. The meter should read "dry" down to the first few inches, at least, between waterings.
