I use the DMT plate to flat my stones, if the stone 24 or 60 grit (like Nubatama Ume) can I use this plate or there is other way to flat it...

You can still use it to flatten those stone's. However, if they're dished a lot.....flatten them somewhat on a sidewalk or some such first....then finish with the plate.

I wouldn't, it will chew up your diamond hone.
I have a 60 grit and don't even bother to flatten it. It's not a very good stone to begin with so I only use it to flatten other stone which it's not very good at either.

I can't imagine ever needing a 24 or 60 grit stone when any repairs or thinning can be done quickly with plates in the 140 range.

2x72 ceramic belts work way faster.

Not if you don't have one.

Actually, gluing coarse belts to a board makes for a great coarse "stone", much faster in most cases. Home Depot sells some diablo belts that work well for this.
Back on subject,
To flatten such coarse stones a lapping powder and a hard surface tends to work best. I would go with 36 grit powder.

Sidewalk is a good suggestion. I never use super coarse stones either btw. 150 Nubatama is about as low as we go with stones.

That's an awesome idea.....never thought of that.

I think I would use a drywall sanding screen as a flattener for such coarse stones. This one is 100 grit
, but you can get them in 220 grit, too.
