My doubt is whether I can use different filters to filter an image (Noise removal) in the same code ? Is the approach right?

I wanted to process an image to remove noise and tried with a particular filter that worked but the MSE and PSNR Values were dis-satisfactory so I again introduced another filter in the same code to Process further the already filtered image. Is my approach correct?

If you were happy with the results, then yes, it was correct. For example maybe you first want to get rid of impulse (salt and pepper) noise with a modified median filter then follow it up with "BM3D" or "non-local means" for superior noise reduction. Then you might even follow that with spike filtering in the Fourier domain to remove periodic pattern noise (if you have that in your image).
