There are 4 purple squares. You cannot make a group of 5 from 4 squares.  
The number of groups is 0.
$$
\text{Sehlopha se tee (1) sa di-5: } \boxed{0}
$$

There are 10 pink triangles.
$$
10 \div 5 = 2
$$
The number of groups is 2.
$$
\text{Dihlopha tše 2 tša di-5: } \boxed{2}
$$

There are 15 blue circles.
$$
15 \div 5 = 3
$$
The number of groups is 3.
$$
\text{Dihlopha tše 3 tša di-5: } \boxed{3}
$$

There are 6 green squares. If we consider groups of 5, it's 1 group of 5 and 1 left over.
$$
5 + 1 = \boxed{6}
$$

There are 3 groups of 5 yellow stars.
$$
5 + 5 + 5 = \boxed{15}
$$

There are 2 groups of 5 orange squares.
$$
5 + 5 = \boxed{10}
$$

*   For 10 items:
    $$
    10 \div 5 = \boxed{2} \text{ dihlopha}
    $$
*   For 8 items:
    $$
    8 \div 5 = \boxed{1} \text{ dihlopha (with 3 left over)}
    $$
*   For 6 items:
    $$
    6 \div 5 = \boxed{1} \text{ dihlopha (with 1 left over)}
    $$
*   For 4 items:
    $$
    4 \div 5 = \boxed{0} \text{ dihlopha (with 4 left over)}
    $$
*   For 2 items:
    $$
    2 \div 5 = \boxed{0} \text{ dihlopha (with 2 left over)}
