Runs during the play

The play went 6 4 5 6 4 5. How would this be scored? I know 6 4 5 is a run of 3 but would 4 5 6 be a run and then 5 6 4 another and 6 4 5 another again?

6 4 (count=10) 5 (count=15)

6
4 (count=10)
5 (count=15) is 3 for the run + fifteen-2, total 5 points
6 (count=21) is 3 for the run (last three cards played make a run)
4 (count=25) is 3 for the run (last three cards played make a run)
5 (count=30) is 3 for the run (last three cards played make a run)

hand of 20, no?

4 4 4 4 3

Yes! 4+4+4+3=15 for 2, there

Yes!

4+4+4+3=15 for 2, there are 4 ways of doing this so 8 points
Double pairs royal (6 distinct pairs of 4's) make 12 points.
