Guys,

Does STM32F103XX series have a pin compatibility with STM32F105xx, 107xx and 207xx ? Any ideas will be appreciated, Thanks

The pin compatibility of various STM32 family parts is generally quite good, but attention needs to be paid to supply pins, and regulator caps. There are a handful of pins you'd want to be able to strap high/low depending on which part/foot-print is being used.

These topics get some coverage in the Data Manuals, and app notes, and can perhaps be visualized in tools like the

That depends on how considered the original design was, particularly the supply/vcap pins, and perhaps the strapping of a few other. I have a design using an F2, a simple BOM change permits F1 or F4 placement.
