A triangle has no right angles when it is not a right angle triangle as for example as in the case of an equilateral triangle that has 3 equal 60 degree angles.
There are no obtuse angles in a right triangle. A right triangle consists of one right angle and two acute angles.
Yes. A right triangle is a triangle where one angle is a right angle. If two out of three angles are right angles, then it's an isosceles triangle. If all three angles are right angles, then it is an equilateral triangle.
An obtuse triangle can have no right angles, and has two equal angles.
A right triangle can have 2 equal angles if they are each 45° (any other right triangle will have no equal angles)

A triangle can never have three right angles
Yes. A right triangle is a triangle where one angle is a right angle. If two out of three angles are right angles, then it's an isosceles triangle. If all three angles are right angles, then it is an equilateral triangle.

That depends what you mean with "other angles". For example, if you are considering a triangle, the sum of all angles must be 180 degrees.
If a triangle is an isosceles triangle as well as being a right-angled triangle, the size of the two angles (that are not right angles) are 45 degrees.
square has 4 right angles and triangle has no right angles
0. A triangle can either have no right angles or it can have 1 (in which case it is a right angle triangle).
a right triangle has one right angle and two acute angles
An equilateral triangle can't be a right triangle since an equilateral triangle has all 60° angles, which are NOT right angles [measuring 90°]. If a triangle is a right triangle, then it has a right angle!
