Triangles can be constructed with three angles whose sum adds up to 180 degrees.
There can be one triangle constructed in this case, UNLESS mirror images of unsymmetrical triangles are counted as two.
(QUESTION IS NOT CLEAR ABOUT COUNTING MIRROR IMAGES AS TWO OR NOT).

Triangles can be constructed given three sides IF the sum of the two shorter sides is greater than the third side (this is called the triangle inequality).
(AGAIN QUESTION IS NOT CLEAR ABOUT COUNTING MIRROR IMAGES AS TWO OR NOT).

ASSUMING mirror images count as a single triangle, then
1. one triangle (sum of angles = 180)
2. none (sum of angles = 210)
3. none (5+5<16)
4. 1 (6+7>9)
5. none (3*63=189 >180)
#1 is one
#2 is none
#3 is one 
#4 is one
#5 is none
