Related to Graph-API, here are the limits known:

Name:

{
  "error": {
    "message": "(#100) name parameter cannot be longer than 1000 characters.", 
    "type": "OAuthException", 
    "code": 100
  }
}

Caption:

{
  "error": {
    "message": "(#100) caption parameter cannot be longer than 1000 characters.", 
    "type": "OAuthException", 
    "code": 100
  }
}

Link:

{
  "error": {
    "message": "(#100) link too long", 
    "type": "OAuthException", 
    "code": 100
  }
}

回答2:

If the message is a status update (that is, you're not including an attachment or an action link), it can contain up to 420 characters. Otherwise, if the post contains an attachment or action link, the message can contain up to 10,000 characters.
