I want to access USB stick using STM32F205ZC. Whether keilV4.20 and st-link debugger will support debugging for OTG or not any suggestions please.

Depends on what debugging you expect it to be able to do.

If it is timing sensitive, then a debugger pod stepping or breakpointing is too invasive. Suggest you attach a serial terminal, and output controllable levels of debug/telemetry data. Have a U-Link or J-Link to hand in case the ST-LINK doesn't cut it. Frankly I've found the ST-LINK's to be more than adequate, but then I'm not constantly single-stepping my own code to figure out how it works. YMMV

Is it preferable to consider

 STM32F105VC or 

 STM32F107VC (OTG) for 

USB stick access?(are there are any limitations or problems we may get if I use these ICs)
