And sir another problem is that the Blu baby will weigh up to 800 gms and my setup can lift maximum 650 gms (as of my knowledge can be wrong)...

It's not a helicopter that has to LIFT its weight.

Sir read that one ( got to know a lot)...so sir which plane would you recommend which is not very tough to  fly and probably a FT model ?

Forget the pod and build the BluBaby!

Sir the 33inch version and what prop should I use with it sir ?

Sir should I use a 2.2ah lipo or 1.5 ah ?

As I said before, start with what you have.
Like 1500mah 3s lipo and 8*6 prop.
Just refrain from using full throttle for long.
Later get an 8*4 for your 1500kv 2812 motor on 3s.

If you can borrow a wattmeter, you can check how many amps/watts it draws at full throttle with an 8*6 and 3s lipo. See if it is within the motor's max rating...

And sir how should I get the curve in  the undercamber wing ?

Sir to reinforce it I have a hollow plastic tube can I use that ? And sir  what thickness of depron should I get for this ?

Sir I will try to borrow a wattmeter or get it from somewhere...
