How many letters of AHMEDABAD look exactly the same when each one is seen in the dashed mirror?

A letter survives an upright mirror only if it has a vertical line of symmetry. In AHMEDABAD those are A, H, M and the other two A's: 5 letters. E, D, B and the last D face the other way. (4 misses one of the three A's; 6 wrongly counts E, which is symmetric only top-to-bottom.)
