If you put all 4 gauges into one ui group, they will render in the order you arrange them.
If the group is given a width of (for instance) 16, and each gauge width is set to 4, then they will all fit into a single row (assuming your screen is wide enough).
Not sure what you mean by "Dashboard arranges all icons among each other" -- but if this does not help you, please post a picture of what you are seeing.
