and also i have another and again thank you for your time.......is it correct to say that that the intake stage of engine opperation is directly following the power stage?

NO.
The intake valve must be open and the piston must move down on the intake stroke to make room for the air to rush in and fill the cylinder.
NO.
After the power stage, the cylinder must remove the used up fuel and the exhaust gases. The next stage/stroke after power would be exhaust stage
Hope that helps...

All automobiles use what is know as a four stroke engine. On the intake stroke, the piston is moving down toward the oil pan and the intake valve(s) is open. NOTE there are some auto engines with multiple intake and exhaust valves.
The piston reaches the bottom of the stroke, the intake valve closes and piston starts back to top in which is called the compression stroke. At or near the very top of the stroke, the spark plug fires and ignites the air/gasoline mixture. The hot expanding gases push the piston down in what is known as the power stroke. Near the bottom the exhaust valves opens and the piston pushes the hot gas out as it comes back to the top in the exhaust stroke. Near the top, the exhaust valves closes, the intake valve opens and it starts all over again.

No and no.
As the piston travels down from TDC the intake valve opens and air/fuel is drawn into the cylinder. Then the intake valve closes before the piston comes back up. As the piston reaches the top, the plug fires. The explosion of the air/fuel forces the piston back down. Then as the piston rises back up, the exhaust valve opens and the burned gasses exit into the exhaust. As the piston reaches the top, the exhaust valve closes. then the cycle starts all over again.
This is for a modern 4 stroke engine.
2) Intake, Combustion, Exhaust. is the order of things.

No. On a four stroke engine (as found in just about ALL cars, light trucks, piston-powered aircraft and MOST street motorcycles), the simple answer is that the intake valve is OPEN and the piston is moving DOWN, which draws the air/fuel mixture into the cylinder.
The sequence of operation is as follows: Intake-Compression-Power-Exhaust

No, the intake opens right as the ex valve is closing at the top of the ex stroke, so the intake charge may be drawn in when the piston is on its way down.

definite they could a 2 stroke detroite Diesel engine runs with no intake valve and a spark plug. And a rotary engine like what's in a Mazda rx7 has no valves and no connecting rods. in case you prefer to understand how they artwork i'm confident you will detect it on you tube. the two engines run and run solid the rx7 is a strong and bullet evidence engine won't be able to kill it. And the detroite runs solid and robust yet make distinctive noise and little ability. A 2stroke diesel has exhaust valves no intake and no spark plug

No. Piston starts down, causing vacuum, intake valve open, fuel air mix being drawn it. Piston starts up, both valves close, fuel air mix is compressed. Top of stroke, spark plug fires, piston is powered down, piston starts up, exhaust value opens letting out exhaust products, cycle repeats.
Intake phase follows exhaust stage.

The intake stage would be preceding the power stage. The piston should be near the top but yes moving up during the intake stage.

intake valve open, piston on way down, creates a suction/vacuum to draw the fuel in.
both valves closed, piston comes to top, gets spark, (power stroke) piston forced down,
exhaust valve opens, piston comes up, gas exits through valve (exhaust stroke) exhaust valve closes,
intake valve opens, piston goes down, draws in fuel...
