What is true of it
G5 is G and D — 1 and 5 counted from G.
The easiest of the 5 fingerings below is 350033: 4 fingers, held at the 3rd fret.
None of them uses an open string, so this chord moves up the neck unchanged — the same shape 1 fret higher is the chord a semitone above.
Where its notes are on the neck
The brass dots are G, the root. Everything else is a chord tone with its degree printed in it.
With a different note underneath
G5/D
xx0033
An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
