A triangle can have up to all three acute angles. An equilateral triangle has three- sixty degree angles, which are acute.
1 (APEX) A triangle is formed by three lines. If the ends of two lines meet to form a right-angle (90 degrees), the third line can only form angles less than 90 degrees. 90 + 45 + 45 = 180 the three angles must total 180 degrees.

Just the one.
Only one of them
A triangle can have up to all three acute angles. An equilateral triangle has three- sixty degree angles, which are acute.
If its a triangle then just the one but if it is a square or a rectangle then 4 of them.

Two of them and they must add up to 90 degrees
A right triangle cannot contain any obtuse angles. The right angle represents 90° and the total of all three angles must be 180°. There is only 90° left for the remaining two angles, so neither can be obtuse (greater than 90°).
0. A right triangle, by definition, will never include any obtuse angles.
