Can the word "PLEASE" use in a sentence like this: I please you to come to my house. Heard it from a friend.
No, that would never be said by a native speaker.
I plead with you, perhaps.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
Yes, "please" may function as a verb, as euncu just wrote above.
However, in your original sentence there is no room for "please" as a verb, as Barb_D already said.
"Please" is not an adjective, depending on the situation it can be an adverb or a verb.
Probably your friend meant "I plead you to come to my house," with the verb "plead" meaning "beg".
"Pleased" is an adjective in "I am pleased that you came" = "I am delighted, happy, glad ... that you came".
"Please" is a verb in "It would please me if you came", "Your coming pleases me".
I please you to come to my house. Wrong
It would please me if you came to my house. Right.
