So according to Akashi-san, Traffic Jam and Haine&Kleine characters’ estimated heights are as follows:

Welter - late 180 to early 190 cm. 
Haine - early 180 cm.
Bellboy - late 160 to early 170 cm.
Flurry - late 140 to early 150 cm. Heels and the spikes on her head add about 15 cm on top of that.

Considering the terms “late” and “early” I suppose the ranges should look something like this:

Welter - 185-195 cm
Haine - 180-185 cm
Bellboy - 165-175 cm
Flurry - 145-155 cm
