How can I save multiple things in a table?

Use dictionaries. Dictionaries are an easy way to modify tables so that each item has its own unique name (kind of like how each word in a dictionary has its own definition). For example:

local songs = {
Friday = "268763467",
["The Song of the Cebu"] = "142570249",
Problem = "261244793",
Bills = "165508381"
}

The reason the song with multiple words is in [" "] is because the dictionary will only identify the string without erroring if there are no spaces or illegal characters. However, one-worded titles are allowed without any modifications. To iterate through your dictionary, just write something like this:

for title, songID in pairs(songs) do
    print(title, songID)
end

Your array currently has index values that are integers from 1 to the length of the table. Dictionaries modify the index.
