Sounds like you have a pretty good grouping along the hoses. Now if you can only figure out how to keep the water where you put it. :)

A rough comparison of volumes needed for various vegetables below but keep in mind the type and tilth of your soil will affect frequency and amounts will increase during periods of hot weather. Also most crops will require some extra water at critical development periods such as when tomatoes when setting fruit, broccoli and lettuce when developing heads, filling pods for peas, etc.

So check out the link below (scroll down) for some classification of heavy water needers like beans and onions and the lesser water needers like herbs. It also cover the ones that need consistently moist soil vs. those that prefer to dry out between watering.

PS: Farmer's Almanac has a basic chart too you might want to check out.
