E-flat up to B-natural is an augmented 5th.
E flat consists of 3 flats, B flat, E flat and A flat. E flat to B flat would be a perfect 5th interval as B flat is in E flat major, but because your question was E flat to B, B is a semitone up from B flat, this would mean the interval becomes a semitone larger, and a semitone larger from a perfect interval is augmented. Therefore, the answer to your question is an augmented 5th. Hope this helps :)
augmented 5th, as e flat to b flat is a perfect 5th and b is a semitone above b flat, making the interval augmented
Going from b-flat and e-flat is equal to a perfect fourth interval, which is five semitones (or "half-steps").
The interval between B flat (B♭) and E sharp (E♯) is an augmented fourth or diminished fifth. This is because E♯ is enharmonically equivalent to F, and the distance from B♭ to F spans four diatonic scale degrees. Thus, the interval spans six half steps, which characterizes it as an augmented fourth.
the interval is a 3rd.
The interval from B-flat to D is a major third, regardless of the key.
The interval from a flat (B♭) to a double flat (B♭♭) is a whole tone or major second. In terms of half steps, this interval consists of two half steps: from B♭ to B♭♭. Essentially, a double flat lowers the note by two half steps, creating this interval.
B-flat to C-sharp is an augmented 2nd.

B-flat up to G is a major 6th. Or, B-flat down to G is a minor 3rd.
right hand above middle C B (flat) B(flat)---------- B (flat)-------- E (flat) B(flat) E (flat) -------- B (flat)------- E (flat) E(flat) E(flat) --------- E (flat) ------- ------------------------------------- E (flat)------- -------------------------------------------------------------------------------------------------------------- left hand below middle C E (flat) -------- E (flat) ---------- A (flat)------------------------- A (flat)-------- A (flat) Thats all I know. !
Bb to D is a major 3rd.
