Eat Meal instead of have lunch

[fenglish]

Hi,

Let's go to have lunch at 12:00pm.

Can I say let's eat meal at 12:00pm?

Thanks.

No. It works if you omit 'lunch'.

These are natural:

Let's have lunch at 12.
Let's eat at 12.

When to use the "meal" for "eating" if it is unnatural for "eat meal"?

Here is the "Eating the meal" from Wikipedia for reference:
https://en.wikipedia.org/wiki/Meal

Is it correct and natural for the following sentences:

Let's have breakfast meal and lunch meal and dinner meal together today.
Let's eat breakfast meal and lunch meal and dinner meal together today.

Let's eat breakfast and lunch and dinner together today.

Let's have lunch meal together today.
Let's eat lunch meal together today.

Let's have meal together today.
Let's eat meal together today.

They're all incorrect. Delete 'meal' from most of them.

These are natural:

Let's have breakfast, lunch and dinner together today.

Let's eat lunch together.

Let's have a meal together.
