I remember from the past some one told me that there are grants for felonys 3 types I believe 1 to start a business 2 to go to school and 3 I can't remember the detail"s can you answer my question as to the how and why I can go about doing this??

There are no special grants for felons.

In fact being a felon, makes you not eligible for some grants, If this was a drug conviction, then many grants are not available.

There are no special grants for felons. They may apply for the same ones as anyone else.

There are plenty of scam sites willing to take a fee from felons to supposedly get information on grants.
The only conceivable ones are for education, but most of those are loans these days. There are a few million people with no felonies who can't get a grant, loan, job, or way to start a business.
