this can happend only there :D

Not sure what you really mean. as far as I can see Cici got fouled to get the penalty and then converted the penalty. Pretty normal really.

Yes, or if your corner taker is the same as your penalty taker, a handball in the box on a corner will result in that as well.
The player who drew the penalty gets an assist.

Normal.

Look at David Luiz goal vs Monaco last night , he assisted him self with a header ;)
