How to play Bm7♭5 on ukulele

Shape 1, 2-2-1-2, reading from the G string on the left:

Index finger: E string, 1st fret (F).
Middle finger: G string, 2nd fret (A).
Ring finger: C string, 2nd fret (D).
Pinky: A string, 2nd fret (B).

The pinky takes a note here. Keep it curved and close to the fretboard between chords so it has less distance to travel.
On ukulele you strum all four strings. The top G string is tuned higher than the C, which is why ukulele chords sound bright and close.
