A string under tension has potential energy, which will be liberated as kinetic energy should the string break or be released.
Yes, the density of a string affects its frequency of vibration. In general, a denser string will vibrate at a lower frequency while a less dense string will vibrate at a higher frequency when under the same tension. This relationship is described by the equation for wave speed: (v = \sqrt{\frac{T}{\mu}}), where (v) is the wave speed, (T) is the tension in the string, and (\mu) is the linear mass density of the string.
Clapping hands is not a tension force. Tension force is a pulling force exerted by a string, rope, or cable when it is pulled tight by forces acting from opposite ends. Clapping hands involves a compression force exerted by the hands coming together.

Yes, a catapult has potential energy when its arm is pulled back and loaded with a projectile. The potential energy is stored in the arm's position and is released when the arm is released, launching the projectile.
Yes. Energy is a scalar quantity. Doesn't matter what kind of.
yes because, as the string gets tighter it will be harder for the string to move
Yes

yes, it's kind of like a guitar but smaller and with more strings
Yes. Think this way. Say you have a 10 pound object supported by a single string system. The tension on the string is 10 pounds, and you must exert 10 pounds of force on the string, so that is (1:1). Now say you have a system where 2 strings support the weight. Each string has the same tension, which is 5 pounds, and you only have to exert 5 pounds force on the string (2:1 for 2 strings).
Yes, because in drawing the string back you put potential energy into it.

Yes it is. It is not recommended to do this all the time though, as each gauge string exerts different stress and tension on the guitar neck. It's best to do this only until you can get yourself new strings.
yes
Yes, although it would be more accurate to say that it has energy.
