I'm rewiring part of my lounge light circuit to include six small

Is there a limit to the number or lights that should come off one
junction box?

The limit is whether the cables will physically fit. Lighting circuits
are radials so there is not the issue of point loads that has to be
considered with rings.

2 lights per JB seems sensible and reasonable.

I ask as I plan to extend the kitchen circuit to three fittings,
all quite near, and it seems that one box could do it for all three.

Kitchens is Part P.

Bear in mind that *each* point on a lighting circuit must be considered
to be 100W or actual load if greater, with no diversity. The assumption
is that all the lights could be on at the same time. Max load on a 5/6A
lighting circuit is about 1200W or 12 points, so unless your circuit is
already very lightly loaded you will probably be non-compliant with the
Regs.
