In brief: No
If anemia develops slowly, your body adjusts to the slow reduction in oxygen carrying capacity, and this compensation prevent the development of symptoms.
In this context, anemia can become quite profound before any symptoms manifest. If anemia develops quickly, however, symptoms are quick to appear.

Not always. However, if allowed to go far enough, you may start to have a lot of lightheadedness, fatigue, trouble with dizziness when rising from a seated or lying position, and then eventually chest pain due to lack of oxygen to the heart.

Not always, especially if it is mild.
If there is a possibility of anemia, you should have a blood count.

In brief: No
In the beginning, especially if the anemia is slowly progressive, you may not notice anything.
Once your hemoglobin gets very low, you will likely be short of breath, have reduced ability to exercise, be tired, and cold. If the anemia is from a rapid blood loss, you are more likely to notice the symptoms.

Anemia develops in most case very gradually so symptoms are non-existenst early on.
Once the red blood cell count drops to less than 10 grams ( normal is 13--14 grams and each whole number is about 1 pint of blood) vague feelings of tiredness and poor exercise tolerance appear. These symptoms will worsen over time until anemia is corrected.

In brief: No
Anemia is defined as a hemoglobin below the normal level.
Normal in men is 13 mg/dl and women 12 mg/dl. Most patients do not experience symptoms until there hemoglobin is below 10.

In brief: No
The faster anemia comes on, the more dramatic the symptoms.
If one were to lose 2-3 pints of blood over 2 hours usually there would be symptoms. On the other hand, it is possible to lose the equivalent of several times that amount over months or even years, have a severe anemia and not have any symptoms.

When anemia is caused by sudden blood loss like an auto accident or severe laceration the symptoms start immediately.

It depends how severe it is (how low is the blood count) and how fast it happenes, (acute vs chronic), also symptoms could get worse with the level of activities.
