Solution:
All the five coasters are based on the layout of the
Inverted Coaster prototype by
B&M called "Batman-the Tide" from Six Flags Great America.
The coaster I searched for are:
1. Batman - the Ride / Six Flags Great America / U.S.
2. Great White / Sea World of Texas / U.S.
3. Batman - la Fuga / Warner Bros. Movie World / Spain
4. Diavlo / Himeji Central Park / Japan
5. Batman - the Ride / Six Flags New Orleans / U.S.
The fifth man out was Number 5. And this because of two reasons: this is the first
B&M coaster to be put up as a second hand ride (it appeared before its current location as "Gambit" in Gotemba Familyland/Thrill Valley in Japan), and also because the ride is layed out as a mirror-image of the original ride in Six Flags Great America, that means, after the lift hill the
first drop turns to the right, while the original versions turn to the left (there are two more mirror-image rides like that: Batman - the Ride at Six Flags St. Louis and Vampire at La Ronde).
