That depends entirely on the electrician and his hourly rates as well as what he charges just to show up.
A light switch replacement is typically considered to be minor work, and many states allow such work to be performed under the local "handyman" regulations. A handyman may cost quite a bit less than an electrician for such a job, and his work can be just as competent as an electrician.
There are multiple ways to wire a switch. If power is fed into the switch box, a second light would be wired one way, if power is fed into the light box, the second light would be wired a different way. This seems like it would be a task better given to a qualified electrician or local handyman.
Run the power line to a light box in each room, then drop a switch leg from each light box. The power line should daisy-chain to each box, with a "tap" off for the lights of each room. If you do not have experience with lighting or switch logic, it would be much more safe for you to contract with a qualified electrician.
You would need to purchase a duplex switch. As for the pilot light look for a duplex switch that has a neon pilot light that is incorporated into the handle of the switch. When the switch is turned on the switch's handle will illuminate.
Assuming your under counter lighting is 120v and is fed from a box installed in the cabinet, you need a competent electrician to run a switch loop to a switch in the wall. He/she may need to make holes in your wall you may not want. There is no magic to getting wires in the wall. The wires can be run exposed if the proper materials are used. This would prevent any undesired holes in your wall.
This depends on the specific way your installation is wired. Most likely, though, you will not be able to just change one light fixture to an outlet. Lights that are controlled together are wired with a common hot wire called a switch leg. This switch leg is connected to the switch so that when the switch is on, the wire is hot. This lights your fixtures. To change a light fixture into an outlet, you need a constantly hot wire. This wire is connected to the light switch screw opposite the switch leg. In your situation, you probably need to run new wires to the new outlet which carry this constant hot and a neutral. Or you would have to bypass the switch (wire nut the hot and switch leg together) and install outlets at both light fixture locations. Simply stated, this is not really an easy fix but more of something for an electrician to do. ----If you do not understand the work well enough to accomplish it yourself properly and safely, don't try it. Consult a professional electrician, as they are proficient enough to do it properly and safely. When working on electrical circuits and equipment, make sure to de-energize the circuit you will be working on. Then test the circuit with a definitive means to make sure it is off (multimeter with metal tipped leads, voltage tester with metal tipped leads, etc., NOT a non-contact tester, which is not definitive.)

This type of reversal in a switch can happen due to a wiring issue or a malfunction in the switch mechanism itself. It is important to have a qualified electrician inspect and repair the switch to ensure it is functioning safely and correctly.
It's because they are not wired in a 3-way fashion. The switch downstairs is wired in series with the switch upstairs in the same manner the pullchain on a light socket adapter would turn on and off your light only when the wall's switch is on.
For the most convenience, you should consider replacing two switches with just one switch that does both tasks. The first thing to do before repairing anything electrical is turn off the electricity to that room, then repair or replace the switch as you would any other light switch.
It is unlikely that you would get shocked from a broken light switch, since they are always made from non-conducting plastic. If you open it up and try to fix it, you might get shocked then. If you turn off the correct circuit breaker or fuse, you can avoid getting shocked when you work on your broken light switch - but if you don't know what you are doing, get a qualified electrician to do it for you. Electrocution is no joke.
Repair or replace your reverse, neutral safety switch.
Yes, you need an electrician to install a power generator and it is very important that he is licensed otherwise it would not work/is not legal. Hire the licensed electrician to install a transfer switch.
i think light two would turn on because it is in the middle of switch a and b

a light switch
It's not suppose to sizzle, you need a new light switch! It might start a fire!! When a switch makes a noise when turned on, this would indicate a quite worn switch or a switch that is not connected properly. The audible noise is made from electricity jumping over a small gap. This jumping does unfortunately create heat and might in worst case cause a fire. It might be easy enough as just tighten a few screws in order to correct this.
