1) NPC cannot learn the spell "message". It's exclusive to players. If one wants to contact another without being a player, he/she needs to use a "message scroll".

2) In the anime, it wasn't thoroughly explained but Ainz tried to contact all of his friend list, then Sebas Tian answered after receiving the message. In the LN, it was Ainz who contacted Sebas Tian and added him in his contact.

3) You can chat using "message" as long as you don't disconnect or end the connection. There's no time limit.
