That is old, but if it's in good shape it should work. I'd keep them about 16-18 inches above the canopy. If you put your hand under the light right above your plants and it's hot you should raise them. Also you can put a thermometer under the the light where the plants are right St the top of the plants and take a temp lo try it out you'll be able to tell if they aren't liking it.

A 250w hps can usually cover a 2x2 to 2.5x2.5 area pretty well so depending on your growing techniques and strain that's how you'll tell how many plants you can grow
