I'm not sure I would use this location for this purpose at this time of year.
Haytor will be crawling with tourists so you will have an audience. Additionally you have chosen the most accessible and popular routes on the tor, as a result you may find others wanting to lead, solo or top rope them as well. Additionally there are various outdoor groups who lash the West Face with ropes and monopolise it for large chunks of the day.
At the very least I would suggest considering a plan B or C.
If I had the same objectives as yourself I would consider driving for another 5 minutes to the Hound Tor car park. I would put my top ropes on some of the friendly little climbs on Greator. You will have the rocks to yourself and can climb in the sun on the South and enjoy the view accross the Becka Brook valley or some nice shady slabs on the North side. You also have the Plan C option of some climbing and bouldering at Hound Tor.
I think your party would get more out of this location and you will have less bother with third parties.
Enjoy your day out.
