Answer 1

This code should give you the idea:

while :; do
    echo "$RANDOM"
    echo "$RANDOM"
    echo "$RANDOM"
    sleep 0.2
    tput cuu1 # move cursor up by one line
    tput el # clear the line
    tput cuu1
    tput el
    tput cuu1
    tput el
done

Use man tput for more info. To see the list of capabilities use man terminfo
