Yes.
Some ways in which an object can become charged are friction, contact and induction.
A positively charged object. Like charges repel.
A negative charge attracts a positive charge and repels a negative charge. OPPOSITES ATTRACT ;)
A positive electric charge creates an electric field around it and interacts with other charges. It repels other positive charges and attracts negative charges. Positive charges move towards areas of lower voltage in an electric field.
No. When discussing an "electric field", we are actually referring to the electrons contained within an object. A "positive electric field" just means that the charge of the object is positive due to the lower amount of electrons in the object. A positive electric field will still in fact attract a positively charged object because there is still an attraction between protons and electrons. In short, the answer to your question is no.
You can tell when an object has been statically charged if it attracts or repels other objects, causes a spark when touched, or gives you a mild shock when you touch it. Objects can become statically charged through friction or contact with other charged objects.
Some neutral objects have a weak dipole force where electron distribution is random across the whole object, and at any one given time, one side may be slightly more positive than the other. This attraction is very weak but it happens frequently especially in solutions.

a negatively charged repels a positivley charged object
The electrical force can repel as well as attract. Like charges (positive-positive or negative-negative) repel each other, while opposite charges (positive-negative) attract each other. An example of this is when two positively charged particles repel each other, but a positively charged particle and a negatively charged particle attract each other.
Yes; positive attracts negative, or vice versa. There is also electrostatic induction: if something is charged and is moved near another object, it repels or attracts electrons (only), giving it opposite charges, so attracts each other. The object which is electrostatically induced is overall neutral, however, it is unbalanced withe negative electrons pulled to one side, leaving the opposite side positive.
A neutral body can be charged negatively by induction when it is brought close to a negatively charged object. The negatively charged object repels electrons within the neutral body, causing the electrons to move towards the opposite side, leaving that side with a net positive charge. This results in the neutral body being negatively charged on one side.
