No because an obtuse angle is greater than 90 degrees and a regular triangle is an equilateral triangle that has 3 equal 60 degree angles that add up to 180 degrees.

No because an equilateral triangle is a regular polygon whereas an obtuse triangle is irregular
No - not a plane triangle. The angles of a regular triangle must be equal. So an obtuse triangle, if regular, would have three obtuse angles. The sum of the angles would then be greater than 3*90 = 270 degrees. But the sum of angles of a triangle must be 180 degrees.
