Split a variable!

Questions
1

Hi dear friends
In my case:
I set a variable from my webhook by “set node”:
myvar = my_name_is_meysam_001

I want to split “myvar” by “_” and split it to 5 new variable like these:
var1 = my
var2 = name
var3 = is
var4 = meysam
var5 = 001
and finally use them in my next nodes.

Can anyone help me how can do this please?
Best regards;

You can split them like this:

Is there any way of doing this but instead of returning it to the same item duplicating the item with the new data?

Example:

Names: John & Bob
Right now split would be Name1=John Name2=Bob

I would want

Item 1: ID: 1 Names: John
Item 2: ID: 1 Names: Bob

Would that be possible?

Check the example below:

{
  "nodes": [
    {
      "parameters": {},
      "name": "Start",
      "type": "n8n-nodes-base.start",
      "typeVersion": 1,
      "position": [
        250,
        300
      ]
    },
    {
      "parameters": {
        "values": {
          "string": [
            {
              "name": "names",
              "value": "John_Bob"
            }
          ]
        },
        "options": {}
      },
      "name": "Set",
      "type": "n8n-nodes-base.set",
      "typeVersion": 1,
      "position": [
        610,
        300
      ]
    },
    {
      "parameters": {
        "functionCode": "const results = [];\nconst names = items[0].json.names.split('_');\n\nfor (const[index, name] of names.entries()) {\n  results.push({ json: { id: index, name: name } })\n}\n\nreturn results;\n\n\n"
      },
      "name": "Function",
      "type": "n8n-nodes-base.function",
      "typeVersion": 1,
      "position": [
        840,
        300
      ]
    }
  ],
  "connections": {
    "Start": {
      "main": [
        [
          {
            "node": "Set",
            "type": "main",
            "index": 0
          }
        ]
      ]
    },
    "Set": {
      "main": [
        [
          {
            "node": "Function",
            "type": "main",
            "index": 0
          }
        ]
      ]
    }
  }
}

Hmm, That does indeed return the 2 names but i ment more as in it duplicates the original row that came in so all the original data is included and the id doesnt change

Hmm, I think i got this to work with a merge node in Multiplex mode to merge the results back together
