My crl is 55125 in B.ARCH . kindly guide what is the rank AND CAN I GET SEAT

Here you haven't mentioned which exam , you have cleared with a rank 55,125. For Architecture popularly JEE paper-2 or NATA. No assuming you are a JEE general candidate , I am answering this question.

Sorry to inform you that , there is a very small possibility for you to get a seat in NIT's or other government funded institutes. The average expected cut-off for 2020 is going to be in a range of rank with 5,000 for general candidates.

You follow up this link for more information regarding the cut-offs corresponding to the colleges following this link:
