1) yes...you can have them on a 18/6 or 24/0 (light/dark) hour schedule.
2)No...get yourself at least some CFL's (compact flourescent lights) for under 10 bux
3)They will get too big once you get CFLs...also, they shouldn't be in the same pot. (1plant/1pot)
4)Same answer as question 2
5)That pot size is fine IF you have 1 plant per (1) 6" pot

Get some CFLs and get your plants on a consistant, regular light schedule (either 18/6 or 24/0).
