        "opposite": true,
        "min": 0,
        "title": {
            "text": "y2",
            "style": {
                "color": "LightCoral"
            }
        },
        "index": 1
    }

Answer 1

It is showing. There's no ticks, though, because you haven't plotted any series against it. On your 2nd series add:

        "color": "LightCoral",
        "suffix": "€",
        "tooltip": {
            "valueSuffix": "€"
        },
        "_symbolIndex": 1,
        "yAxis": 1 // ASSIGN series to it
