YES and NO
You can usually get a small kite flying in very low wind by flying the heck out of it and creating your own apparent wind.
A larger kite is needed to create enough power to ride in lower wind. The larger kite will turn + fly slower so in many ways it is more fun to fly a
small kite in low wind. The larger kite is needed if you need power.
5m is a good size . It can be flown fast but has enough size to give you some power as well.
Not all 5m ( or other ) kites are the same !!!!! Shape and bridles make them fly very different.
