I need Electric Help... Any electricians out there?

If you tap on the fixture will it flicker?

Could it be it happens when I have my air conditioning running?

Central air or standalone unit?
Are the lights flickering or dimming?

Central air. Flickering slightly. Enough to give someone a real headache if they care.

Dimmer connected to it?

Dimmer connected to it?

One of them yes. Others not.

So this is more than one fixture in different locations?

Two easy options.
1. Each switch has a line wire and a load wire. Combine the 4 line wires and a pigtail, combine the 4 load wires and a pigtail, connect to one of the switches. The other 3 switches are defunct.
2. Add another switch that will control the existing 4 switches. Remove the 4 line wires from the existing switches, combine and connect to the new switch. Attach a new wire to the load side of the new switch that runs to the line side of the existing switches and you're done. Now you have a "master" switch that controls all 4 at once, but also still have the individual switches that control 1-2 bulbs when the master is on.

I'm assuming here that you have 4 individual line wires which is very unlikely. You probably just have 1 which is split off into 4, so the actual work is even easier. Pictures would definitely help here.

I will send pics later.

Do not do this unless you know where all the wires are coming from.
ETA: After thinking about this for a little bit I have a new recommendation. 
DON'T DO THIS!!!

Hopefully the pics will clear your concern

My concern is if you do that you might not be around to post pics.

In all my bathrooms and some bedrooms, I have these lights. https://www.lowes.com/pd/Project-Source-2-Pack-14-in-Brushed-Nickel-Transitional-Integrated-LED-Flush-Mount-Light-ENERGY-STAR/1001042584
None of them have a dimmer switch. And they sometimes flicker very slightly.
In some bathrooms I also have this one which does have a dimmer. https://www.lowes.com/pd/Project-Source-3-Light-Chrome-Traditional-Vanity-Light-Bar/50254179 which also flickers slightly.

Of course anyone is welcome to not do this, but there's no reason not to if they want.

But how is one switch currently controlling 2 lights? Is it because 2 load wires are connected to the one switch and I just don't see it?

It's possible but more likely that the same load wire runs to both the first light and the second.

I have done this in my house (for 2 switches) so if I get a chance I'll open up the wall plate and take a pic.

[yos9694]

Should go without saying but my suggestion is based on the assumption that all 4 switches are controlled by the same circuit breaker. If that's not the case - don't combine the wires.

That brings me to my next question, it's a track, how are the wires running to the lights, they are all on the same track?

You'd need to find the wiring diagram or take some really good pictures to answer that. But its not shver- the wiring could have been designed for individual control, just like how ceiling fan wiring is designed for making separate switches for the light and the fan (extra load wires).

It sounds like an under power issue. The AC could be the problem.

We are all here to help. When it comes to electricity which can be extremely dangerous we should be cautious. What you are suggesting can be dangerous. Think about this for a minute.

[CountValentine]

If your assumption is wrong it is a disaster waiting to happen.
If your assumption is right then there is no need to connect all four line wires together.

[CountValentine]

That brings me to my next question, it's a track, how are the wires running to the lights, they are all on the same track?

Is there one junction box for the lights? If so that is what a pic is needed of. You should be able to solve your issue there.

[Definitions]

I'm trying to switch the coaxial cables circled in red (it's cable internet). How do I unplug the big connector?

 Any safety precautions that I should know of? Should I put on silicone grease when connecting the cables?

The green circle is a wire that looks like a ground wire or something its hooked on to a metal bolt.

I don't know what the blue wire is. Might be a regular telephone line.
