You can use:

KERNEL=="comedi[0-9]", MODE="0666"
KERNEL=="comedi1[0-5]", MODE="0666"

Or if you're not so fussy about matching device names:

KERNEL=="comedi[0-9]*", MODE="0666"

For the safety conscious, it would be better to add a "comedi" group
using the groupadd command, add allowed users to that group using the
gpasswd command, and use MODE="0660" and GROUP="comedi" in the udev
rules to create the comedi devices with suitable permissions:

KERNEL=="comedi[0-9]", MODE="0660", GROUP="comedi"
KERNEL=="comedi1[0-5]", MODE="0660", GROUP="comedi"
