When a circuit breaker trips it must be fully moved into the off position and then back to the on position. It sounds like you have tripped the breakers and this is the normal function to reset them.
The problem is "why did you have so many tripped breakers in the first place"...
My concern is that you lack the basic understanding of electricity and the terminology, it's extremely difficult to get across what's actually occurring here because of your descriptions. A switch is located in a wall, a circuit breaker is located in the main panel, the GFCI (RCD) is usually located in the main panel in European systems and they usually have two separate GFCI (RCDs) with each covering half the panel.
If you're not comfortable you should call a professional, this answer is hated my the mods and they likely will delete this (like my last suggestion to call a professional) but safety is the top priority here.
Check the appliances and cords to see if there's any obvious damage to them, check to make sure you're not drawing more current than the branch circuit is rated for, and obviously have a GFCI (RCD) installed if there's not one already in the main panel.
