The interval from B-flat to D is a major third, regardless of the key.
B-flat to C-sharp is an augmented 2nd.
C major: no sharps, no flats F major: no sharps, B flat Bb (B flat) major: no sharps, B and E flat Eb major: no sharps; B, E, and A flat Ab major: no sharps; B, E, A, and D flat Db major: no sharps; B, E, A, D, and G flat Gb major/F# (F sharp) major: no sharps; B, E, A, D, G, and C flat / F, C, G, D, A, and E sharp; no flats B major: F, C, G, D, and A sharp; no flats E major: F, C, G, and D sharp; no flats A major: F, C, and G sharp; no flats D major: F and C sharp, no flats G major: F sharp, no flats
b flat, c, d, e flat, f, g, a, b flat
When counted in half steps, B lies between these two notes. It implies that the interval has two half steps. Hence the interval between B flat and C is one whole step, one tone.
Such a key only exists in theory and not in practice. In C-double-flat major, every single note (C D E F G A B C) would have a double-flat on it, and it would sound the same as B-flat major.
B-flat to C-sharp is an augmented 2nd.

Major triads are made up of three notes; a major third interval followed by a minor third interval. An example of the C major triad is C E G. A minor triad has a minor third interval followed by a major third interval, such as C E Flat G.
D flat major, or b flat minor. The flats are B, E, A, D and G, in that order.
b flat, c, d, e flat, f, g, a, b flat
Every key signature that has flats has a B flat. These keys are: -F Major (Also D Minor and G Dorian) Has only B flat. -B flat Major (Also G Minor and C Dorian) Has B flat and E flat. -E flat Major (Also C Minor and F Dorian) Has B flat, E flat, and A flat. -A flat Major (Also F Minor and B flat Dorian) Has B flat, E flat, A flat, and D flat. -D flat Major (Also B flat Minor and E flat Dorian) Has B flat, E flat, A flat, D flat, and G flat. -G flat Major (Also E flat Minor and A flat Dorian) Has B flat, E flat, A flat, D flat, G flat, and C flat. -C flat Mojor (Also A flat Minor and D flat Dorian) Has B flat, E flat, A flat, D flat, G flat, C flat, and F flat.
