You simply move the key down one half step
The way you would modulate from D major to Bb major would be passing through a D minor chord then modulating to G minor to get to Bb major.
The fastest method could be a common tone modulation from D-flat to F, which is then the dominant of B-flat. The D-flat moves to C, the A-flat up to A-natural, and the F carries through.

To enharmonically modulate from G minor, you can pivot to the key of D-flat major by using the note A-flat, which is the seventh scale degree in G minor. In this context, A-flat can be interpreted as G-sharp, leading to a D-flat major chord (D-flat, F, A-flat) which serves as the new tonic. This modulation takes advantage of the enharmonic relationship between G-sharp and A-flat, allowing for a smooth transition to the new key.
To modulate from A flat Major to C Major, you can use a pivot chord that is common to both keys. A common choice is the chord D minor (ii in C Major and vi in A flat Major), which helps create a smooth transition. Alternatively, you can also use a direct modulation by simply shifting to C Major, emphasizing the new key with a strong cadence or a dominant chord (G7) leading into the C Major chord.

I'd do a sneaky semitone raise to A, then its easy to shift from A to D probably using an A7
It depends if you're playing a D flat major or a D flat minor chord. For D flat major, play D flat, F, and A flat. For D flat minor, play D flat, E, and A flat.
15 different key signatures exist.

To modulate from D major to E major, you can use a pivot chord that is common to both keys. A suitable pivot chord is A major, which functions as the V chord in D major and the IV chord in E major. Alternatively, you could use a direct modulation by moving to an E major chord after establishing the D major tonality, signaling the shift clearly. This modulation can also be enhanced with a leading tone, like C♯, that resolves up to D in the transition.
