Could it also be "I knew many fun people"?
Usually the preterite (conocí) indicates the (single) first time you knew them, so "met."
The imperfect (conocía) indicates the action occurring over time, so "knew."
Lo conocí. I met him. Lo conocía. I knew him.
Could you also say muchas personas divertidas? Is there a rule for using one over the other?
What s "a" for ?
The "a" is the personal a.
Thanks Spud, that answers one of my earlier questions as well.
Conici means met or know so my answer should have been accepted whether I indicate met or know
Conozco - I know
Conocí - I met
Some verbs have a different sense in the preterite.
Here is a good site to help understand the "personal a
Can gente be used singularly as in translated as person rather than "a people" or must you used persona?
No. The word 'gente' is a group noun. It always means plural (but just so no one misunderstands... the word is grammatically treated as singular: la gente, not las).
