I suspect those challenges are difficult for everyone. Getting the ball to stop is key...and with starter equipment and balls, applying
the right amount of spin is tough. Pay particular attention to
wind speed and direction. A headwind (in your face) will stop the ball
much quicker than a tailwind.
A hint for #6 is to go a little long...using the back boards on the back of the green that allows the ball trickle back down to the hole.
