It's likely the Sofreh Mahi however that craft is too small to be a useful Jet powered UAV unless it's a scale down model of a UAV.... I would assume that the success of the full scale UAV version will likely determine whether they'll ho ahead and turn it into a manned fighter....
As for the Q-313 that plane was an embarrassment from the start... To me Q313 would of at best been a good Tech demonstrator of a low end Iranian Aviation University designed by a bunch of university students and developed and built using PANHA infrastructure. And NOTHING MORE! I honestly hope their developers prove me wrong however I have always seen it as a failed project and at best nothing more than a tech demonstrator...
As for the Sofreh Mahi models I think If they can add 2D TVC with strong enough engines I would go with the one that looks like this

However if TVC is no possible then the one below would be my choice however the location of the intake would need to change.....
