The relative minor to G Major is E minor.
The corresponding minor key to G Major is e minor. The key signature will be the same, one sharp: F#.
The relative key is the one with the same key signature. For C major, it's A minor.
The relative minor of a key signature is the key three semitones, and two letter names, below the major key in question. For example, the relative minor of A major is F# minor (three semitones, two letter names down). The relative minors of the correpsonding major keys are as follows: C - A minor Db - Bb minor D - B minor Eb - C minor E - C# minor F - D minor G# - Eb minor G - E minor Ab - F minor A - F# minor Bb - G minor B - G# minor
The relative major key of Gb minor is Bbb (double-flat). However to make life easier, one could just say the minor key is F# minor and then the relative major would be A.
The key of E minor has one sharp: F sharp. It is the relative minor of G Major.
If I understand your question correctly: G minor has two flats, as does B flat major.
E Minor is the relative minor to G Major.

The key of G-sharp minor has 5 sharps (it's the relative to B major). G-flat minor is a key that only exists in theory, because that key signature would contain 9 flats. The limit on flats or sharps in a key is 7.
E Minor is the relative minor to G Major.
both C major, and it's relative minor, A minor, contain the notes D, F, G, and A.
Bb. B flat has two flats, the first two flats on the staff: Bb, and Eb. Also, the relative minor to Bb, G minor, also contains two flats in the key signature; Bb, and Eb. To find the relative minor to a major key, simply count down 2 and one half steps. ie: Bb, Ab, G, making the relative minor to Bb "G minor", which also has the same key signature.
