No. It is not possible to make a equilateral triangle that is obtuse.
Yes, its not possible to have a "right obtuse triangle"
no
In normal geometry, it's not possible to make a triangle with two obtuse angles. It is possible to make a triangle with two obtuse angles in spherical geometry -- it's a kind of "spherical triangle". It is possible to make a triangle with two obtuse angles in some kinds of non-Euclidean geometry -- it's a kind of "non-Euclidean triangle".

Yes it is possible to have a obtuse scalene triangle.
Yes, its not possible to have a "right obtuse triangle"
no
The definition of an obtuse triangle is a triangle with an angle exceeding 90o. A scalene triangle is a triangle in which no two sides are of equal length. Therefore, it is possible that an obtuse triangle is a scalene triangle. However, it is also possible for an obtuse triangle to be an isosceles, in which two sides are of equal length. On a final note, it is impossible for an obtuse triangle to be an equilateral; equilateral triangles always have angles of 60o.

No
No, those three examples cover all possible cases. If it is a triangle, then it is either acute, right, or obtuse.
