How can i parse my output?

[DeaD_EyE]

Hm... what if all elements of the 3 lists are packed into one dict?

[{'Manufacturer': 'VMware, Inc.', 'Model': 'VMware7,1', 'Name': 'DC01'}]
[{'Index': '1', 'IPAddress': ['192.168.1.240,fe80::350e:d28d:14a5:5cbb']}]
[{'Name': 'DC01', 'UserName': None}]

The single quotes are invalid for use in JSON.
I look more like Python Code.
You could use ast.literal_eval, which is safe.

from ipaddress import ip_address
from ast import literal_eval


def parse(file):
    result = {}

    with open("data.txt") as fd:
        for line in fd:
            # skipping empty lines with only
            # whitespace
            if not line.strip():
                continue

            for element in literal_eval(line):
                result |= element

    # example to change existing data on result
    # list contains 1 str with many ip addresses
    # the addresses are splitted by a comma
    if "IPAddress" in result:
        ip_addresses = []

        # get the list from IPAddresses
        # and take the first element (there is only one)
        # then split this str by comma
        for ip in result["IPAddress"][0].split(","):
            # creating a IPv4Address or IPv6Address instance from
            # the str of the ip address. Not required
            ip_addresses.append(ip_address(ip))
            # to append only the str
            # ip_address.append(ip)

        # assign the ip_addresses
        result["IPAddress"] = ip_addresses

    return result
