It can be. If you do it once then ussually people dont do anything, but if you are constantley follwing someone, it can be saw as harrasment, and charges be saught after you. Unless it is gov. or police officers they are aloud to, and there is nothing you can do about it. It really just isn't safe either like you can be beat-up for doing it, and then the person can just claim self defense since you were following them.
In general no. If my path happens to take me in the same direction as your path I am not obligated to choose another path. If the following is menecing, threatening or constant than it might be considered stalking. Stalking is illegal in most states but it entails more than simply walking on the same street in the same direction at the same time. There is another consideration though. If your in a state with a stand your ground law such as Florida and you have a reasonable fear of imminent peril of death or great bodily harm to yourself or another such as an armed man following you at night for no apparent reason than you have a right to stand your ground and even use letal force in your own defense. That person following you may not have broken a law but you are not obligated to wait for them to attack before defending yourself in some states. This is a grey area of law since neither person may have actually broken a law but both might be justified in commiting violence by the law. Both the person who feels they are being menaced and the person they attack with leathal force when they stand their ground. Common sense dictates that while following someone might not be illegal it also might not be very wise.
It depends on the extent and the context. Each state has a statute that defines stalking. If the behavior rises to the level of stalking, it is a crime.
Further, if the person is stalking, the victim may be able to secure a restraining or protective order against the stalker.

Not necessarily, if it was just a general picure of people in a crowd. However, if the photo is to be used commercially (or in ANY money-making-type of endeavor) you MUST obtain a "release" from them allowing you to use. it.
