How much dollar to I can meet with everybody in the Disneyland ?

I'm not sure what your question is, but it does not cost extra to meet the characters. They usually have posts in each of the parks and you can wait in line to meet them. There are also character breakfasts available, which obviously are the cost of a meal, but you wait less time to meet the characters.

My answer would be the same as all the others. No cost to meet the characters but you will have to stand in line. The character meals are you best deal but they will cost you.

You just pay to get in then you wait in lines to meet everyone

If you want a character experience, you can see the Winnie the Pooh characters at the Buffet restaurant at Magic Kingdom. The Mickey/Minnie crew is at the Buffet at MGM Studios. You pay for the Buffet, and the characters come to your table for pictures and greetings while you eat. It's great for lunch... Fill up mid day!

It is free to meet any character at all Disney parks. It only cost to get into the park

Exactly. No need to pay extra to meet characters. Just the ticket itself

Samantha is correct. The characters are around the parks and you wait to see them. The character meals are a little pricey but you get more time and one on one attention with them.
