7 on a 15 amp circuit and 9 on a 20 amp circuit.
If each outlet draws less than 2 amps, then you could control 10 outlets with a 20 amp GFCI outlet on a 20 amp circuit. However, it's worth consulting an electrician to ensure the load calculations are accurate and the wiring is safe for the intended use.

GFCI receptacles are designed to trip at around 5 milliamps (0.005 amps) of current leakage to ground. When the GFCI detects this level of imbalance, it quickly shuts off the power to prevent electric shock.
There is probably water in an outside outlet. GFCI outlets monitor the neutral wire, and any moister it detects will cause it to trip out. Also the outlets themselves could have been damaged and need replaceing. The circuit breakers might also be tripped, the GFCI outlet is designed to not reset unless there is power from the breaker. Hope this helps.
This question requires answering by a VERY knowledgable electrician, or an electrical engineer. I am neither, but until the right answer comes along, I will attempt to provide some information which hopefully will allow a better understanding of the issues involved. A GFCI [ground fault circuit interrupter] is much different from, although similar to, a circuit breaker. The DIFFERENCE is WHAT they are designed to detect and react to. The purpose of a fuse or circuit breaker is to detect excess or MASSIVE current flow [ie. a SHORT CIRCUIT, a direct short to ground], and then very quickly turn off the electrical current to the circuit, in order TO PREVENT a FIRE. This is the only thing the breaker is designed and intended to do. This limited capability will not prevent a person from being electrocuted when a fault occurs within an electrical device, if the current flow happens to be low. Voltage and current faults which can kill a person usually will not be detected by a circuit breaker. A ground fault circuit interrupter [GFCI], on the other hand, is designed to, and will, detect those low level currents which can kill a person, BUT which are not great enough to trip a breaker. When a GFCI detects potentially dangerous current it, like a breaker, trips in order to open the circuit. Now as to WHY, when you placed two GFCIs in series [one in the breaker panel feeding one in an electrical receptacle], the first GFCI tripped when the second GFCI is "tested." When you press the TEST BUTTON on a GFCI it puts a high resistance load on the circuit, which simulates a "small" ground fault, and I think both GFCIs "see" the same fault and react as designed and intended. Again, a true professional should "bless" my comments, but I think that there is no danger or hazard in placing two GFCIs in series. On the contrary, I think there is redundant capability in the pairing, with the first GFCI functioning with, and as a backup to, the second. I suggest you contact your local electrial inspection department regarding what the code(s) say about this issue, and also call the tech support people at the 800 number on the packaging for the GFCIs. Another source of information is a local electrical engineer, if you know someone who can help you make contact. Until a more informed answer comes along, I hope this helps you to understand the issues involved.
Typically, you can install multiple GFCI outlets on one circuit, but it is recommended to consult with a licensed electrician to ensure proper installation and safety.
Since GFCI's are more expensive, you wouldn't want to use them in any place where they are not required. In many old homes, GFCI's are sometimes used for outlets in bedrooms and living rooms where proper grounding is necessary (for computers, TV's, other electronics), but not available because of the age of the wiring. You would also want to avoid cramming a GFCI into a box that is too small to accommodate the bulkier GFCI outlet. You should first replace the box to a larger one.
If each outlet draws less than 2 amps, then you could control 10 outlets with a 20 amp GFCI outlet on a 20 amp circuit. However, it's worth consulting an electrician to ensure the load calculations are accurate and the wiring is safe for the intended use.

how many population on haiti from now?
code states that if a water source such as a sink is within 6 feet of a receptacle, that recetacle (s), must be protected by a GFCI receptacle. I believe the actual distance is 5 feet. Please forgive me if I'm wrong. But the NEC also requires that ANY counter top receptacles in a kitchen and receptacles ANYWHERE in a bathroom must be GFCI protected. More directly to your question, ordinary receptacles can be protected from a GFCI receptacle if properly wired. They are designed to do that. It is a way to save money. You may also consider a GFCI breaker if you have many receptacles to protect. I was told once that there is a limit of 3 "piggy backed" receptacles per GFCI but I have never seen that in the NEC.
it depends on the type of element
it has approximately 1000 outlets NIKE
This depends on how many outlets you will need in the home.
Depends on the breaker. If the load at the outlets is unknown then the standard rules of 80% apply. You can only load a circuit 80% of it's maximum value. For instance, if you're connecting your GFCI outlets to a 15 amp breaker you can only have a maximum of 12 outlets. If it's a 20 Amp breaker then you're allowed up to 16 outlets and so on. In the US, you are limited to 13 receptacles on a 20 amp circuit and 10 receptacles on a 15 amp circuit in commercial or industrial installations. Any or all of these can be gfci-protected. You can install one gfci, the first one from the panel, and protect any or all the others from that one.
