Sure. What's wrong with 1 degree, 1 degree, and 178 degrees ?
It's kind of a flat, skinny triangle, but it's a triangle.
***
A valid point, but the triangle described above is not an acute triangle but an obtuse triangle. In whole numbers, 46 deg, 46 deg and 88 deg or 2 deg, 89 deg, 89 deg are the two most extreme ACUTE triangles.
***
An equilateral triangle has three 60-degree angles. All three of those are acute.

Yes it can.
For acute triangle None of the angle of triangle should be more than 90 degrees. See the weblink below for formulas.
Yes. For example an equilateral triangle has 60 degrees in each angle (180 divided by 3 is 60) and since an acute angle is an angle with degrees less than 90, all three of the 60 degree angles are acute. Therefore, you can have a triangle with 3 acute angles.
no an acute triangle does not have a right angle. if it had a right angle, it would be called a right triangle. to be an acute triangle, the triangle needs two angles that are smaller than 90 degrees.
An acute angle is any angle less than 90 degrees.
