A scalene triangle could have three acute angles, one right angle and two acute angles, or one obtuse angle and two acute angles.
If all of the 3 acute angles are 60 degrees then it is an equilateral triangle if not then it could be a scalene triangle.
Any 2 angles that add up to 90 degrees because there are 180 degrees in a triangle and a right angle measures 90 degrees
A Right Triangle measures 180 degrees overall, diveded in three exact sections at 60 degrees.
The word would be acute. You could refer to the triangle as an acute triangle. This means all angles measure less than 90 degrees.
It could have 2 or 3 acute angles

It could, but that's not required. It can have either two or three acute angles.
Yes, but a triangle is acute only if all three of its angles are acute (< 90o).An isosceles triangle can be an acute triangle, but it doesn't have to be.An acute triangle can be an isosceles triangle, but it doesn't have to be.That depends on the sizes of its angle because an isosceles triangle has 2 equal sides and 2 equal angles which could be 70 degrees, 70 degrees and 40 degrees which are all acute angles that add up to 180 degrees.
A Right Triangle measures 180 degrees overall, diveded in three exact sections at 60 degrees.

It could be a number of things. Isosceles triangle is most likely what you are looking for.
