Is this good to give all the exams?

Why not all the exams?
If you have 50% in aggregate in your graduation then you can apply in most of the MBA exams including CAT- for general category. If you have less than 50 percent in your graduation then you won't be eligible for CAT but you can apply for XAT and MAT as the percentage requirement is not mentioned officially.

The applications are ongoing for CAT, XAT and MAT applications have just ended on 25th Aug.

Do not just rely to one entrance. GIve a few.
With CAT you can get admission in its 20 IIM's and many other private institutes.
You can check the complete list here.
Aim at scoring above 93-97 percentile to get in the colleges related to CAT.

Through XAT, you can check the list of participating colleges below: Including 11 XAMI colleges
