No. Look at: https://i.ytimg.com/vi/x1q9MXvjDlM/maxresdefault.jpg That should show you pictures of two, three and four contact mini jack plugs. A two-contact one is used for one audio channel (the two contacts being signal & ground). A three contact one is used for two channels (signal 1, signal 2, and ground). A four contact one is for three channels (eg on a stereo headset which has L & R speakers, but a single mono microphone) - the four contacts being L, R, mic and ground. (The tip/ring/sleeve terms that someone else mentioned are names for the different contacts on a three-contact jack plug.) Which type of plugs do you have on your mics? On 'professional' equipment it gets a bit more complicated when three connections are used for a single audio channel, being the +ve half of a waveform, the -ve half, and ground. (These are known as 'balanced' connections, and typically use either XLR plugs & sockets or 3-contact 6.25mm audio jacks.) -- Jeremy Nicoll - my opinions are my own.
