In linear dynamic systems, the motion traces out an orbit or trajectory in phase space that's a looping curve, mathematically predictable. In nonlinear systems the trajectory in phase space may be a fractal structure, leading to motion that is inherently unpredictable (chaos) from its equations of motion.
Two-dimensional motion that is not always projectile motion would be circular motion, where an object moves in a circular path. Two-dimensional motion that is not projectile motion and does not accelerate the object could be uniform circular motion, where the speed is constant but the direction changes.

The two components of projectile motion are horizontal motion, which is constant and unaffected by gravity, and vertical motion, which is affected by gravity and follows a parabolic path. Both components combine to determine the trajectory of the projectile.
Projective motion is any motion defined in two dimensions. For example, if we mathematically project the three-dimensional path of a flying airplane onto a flat plane, the result is projective motion. The three-dimensional path was projected (thus the term) onto the flat plane..
Circular motion is a type of two-dimensional motion that is not always projectile motion. In circular motion, such as a car driving around a curve or a satellite orbiting a planet, the object is constantly changing its direction without necessarily being launched upwards. This motion can involve acceleration due to the changes in velocity direction.
A motion along straight line is called rectilinear motion. In general, it need not be one - dimensional; it can take place in a two dimensional plane or in three dimensional space. But, it is always possible that rectilinear motion be treated as one dimensional motion, by suitably orienting axes of the coordinate system.

In two-dimensional motion that is not projectile motion, the object may have acceleration even if it is not accelerating overall. This is because the object's velocity can change direction in two dimensions without necessarily changing its magnitude, leading to acceleration along curved paths. Projectile motion, on the other hand, involves acceleration only in the vertical direction due to gravity while the horizontal velocity remains constant.
No, the trajectory of a point is independent of the chosen reference frame. The trajectory is determined solely by the motion of the point, and is not affected by the choice of reference frame used to describe that motion.
