What if i feel am landing in none of the mba colleges and am 4 yrs exprienced

you can try for ISB or one year executive MBAs in IIMs.. its not end of the world if you dont get PGP...

Invest 1 more year, give your best and go for ALL the mba exams. With all the learning from this attempt and the extra effort you will surely land a decent college. 2-3 years of workex is normal, you have a year or two extra big deal. Doesn't matter much.

How many students are taking the XAT mocks? Will be great if @Cracku can also mention the number of students that have taken the mock in the analysis section!

For XAT Mock 1, the number of test takers is given at the end of the analysis, for the rest, just use your percentile and consider the test takers of Mock 1 as a baseline to calculate your rank.
