Ok, look:
Я получил три с минусом is used almost as often as Я получил тройку с минусом but the 1st sentence is shorter than 2nd so it's easy to say it. It depends on your preferences. Кол is more...

The 1st sentence only means The girl's name is Stepanka. The 2nd one means that "The girl's name is Stepanka, neither Natasha nor Ira". BTW Stepanka looks like Bulgarian name.

Как дела у твоей...
