Well, I dont have any information about fighter/bomber iranian project that is actually under development. There are (or were):
1. project Offogh - modernisation of F-5E
2. project Simorgh - modification of single seat machines to improvised two seat F-5F
3. F/B-22 - project of industrial company HESA to rebuild older F-5F to fighter/bomber - it was never realised
4. Azarakhsh - modified F-5E, some 30 were ordered, but only 6 to 9 were really built and its not clear, if they are in service or not
5. Azarakhsh-2, Saeqeh-80 or simply Saeqeh - recognizable thanks to its double vertical tail
6. Tazarve - light jet trainer
7. Shafagh/Shafaq - project based on russian Mukhamedov project Integral (sometimes refered as M-ATF, but this designation was used at leat two times for two different configurations) - now exist only mockup
There are RUMOURS that Iran is working on project F/B-44 that is replacement for F-4 and F-14, but till now there is not any sufficient evidence (official or not) to prove it. If its real, then it is based on.... and now comes the surprise.... on YF-17. Because short after loose with YF-16 and just before islamic revolution, Northrop sold complete YF-17 documentation to Iran. This is proven fact, but I personally dont think, that the project F/B-44 really exist.
Its the same type of situation as now with chinese J-XX. We have dozens of artists impressions how can it look, but after the real J-XX will be revealed, we will be able to conclude, that 99 % of them are simply wrong.
