No. The sine of an angle is not directly proportional to the angle. It is a function of the angle, but it is periodic, repeating every 360 degrees of the angle.
The sine theta of an angle (in a right triangle) is the side opposite of the angle divided by the hypotenuse.

We'll answer your question as asked. What was asked was, "What is the sine of the angle (the angle theta) if the angle measures 0.4384?" That's the way the question reads. That's a pretty small angle. Less than one degree. That angle has about 0.00765 as the sine. Perhaps the question was "What is the angle of theta if its sine is 0.4384?" In the event that this was really your question, if sine theta equals 0.4384, arcsine theta is about 23.00 degrees. Here we use the term arcsine. If we see "arcsine 0.4384" in a text, what it means is "the angle whose sine is 0.4384" in math speak.
No. The sine of an acute angle is less than 1. An acute angle is less than 90 degrees. The sine of 0 degrees is 0, and the sine of 90 degrees is +1. So the sines of the angles between 0 degrees and 90 degrees are less than 1.

No, the angle of incidence and angle of refraction are not directly proportional. They are related through Snell's Law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocities of light in the two mediums.
The result is a direct consequence of the sine rule.
Acceleration is not directly proportional to the angle of inclination. Acceleration depends on the force acting on an object, with the angle of inclination affecting the components of the force acting along different axes. Therefore, acceleration can vary with the angle of inclination but is not directly proportional.
in a series RC circuit phase angle is directly proportional to the capacitance
No
the sine of a 30 degree angle is 0.5
the sine of an angle can't be greater than 1.0
It is 1.
The effort required is directly proportional to the sine of the angle of inclination.Since the sine of an angle increases with increase in angle, therefore the effort required also increases.
Sine of an angle (in a right triangle) is the side opposite of the angle divided by the hypotenuse.
The sine theta of an angle (in a right triangle) is the side opposite of the angle divided by the hypotenuse.
An angle can have a sine ratio, not a triangle.
