"I can get to know and get along well with people"
人 is person
と is the particle and can mean if;when;and;with;and used for quoting. in this case i think it is with
知り合い (shiriau) is to get to know (someone), to make aquaintence. (or it can be used as a noun for an aquaintence).
仲良く (nakayoku) is to making friends with; getting along well with.
できる has a few meanings, though in this case i guess it is to be able to/ can.
I still have alot to learn about Japanese language though, so this could be totally wrong!!
