It means "I know him". There are two verbs in Spanish that mean "to know". "Conocer" is used in relation to people. Factual knowlege is used with the verb "saber". "Lo sé" means "I know it".
It means 'yes I know it/him'.
"No lo conozco" or "A él no lo conozco"
I know (as in to know a person or a place not to know a fact or skill)
Depends... Sé -- e.g. sé su nombre = I know his name Conozco --- e.g. Conozco a Juan = I know Juan Lo conozco = I know him La conozco = I know her Lo sé = I know (that concept/idea) --- If you are just responding to some one saying something you already know, you would say "lo sé" If "I know" is the beginning of a sentence the "lo" changes to "yo". I know where José is = Yo sé donde esta José. I know José = Yo conozco a José If you want to say "I know him" then you use both yo and lo. "Yo lo conozco" Conocer = to know someone saber = to know something (item or idea) Strangely enough if you want to say "I know who he is" you would say "Yo sé quien es." or "Yo lo conozco"(I know him)
