Regarding this, can I add more breakers to my panel?

If there is no open space, local codes may allow you to replace a single breaker with a tandem breaker, which supplies power to two circuits. Make sure you do not overload your service panel. For example a 100-amp service panel may have circuit breakers that add up to more than 200 amps. This is normal.

Is it dangerous if circuit breaker keeps tripping?

Repeated circuit breaker tripping caused by general wear and tear on the circuit breaker is usually due to one of the following issues: Short Circuit: A short circuit is common, but potentially dangerous. The circuit breaker automatically shuts off in cases like these to prevent an electrical fire.

Subpanel main breaker

A main breaker on a subpanel is not necessary because this is in the same building (if you are in a different building then NEC 225.31, 225.32, 225.33 apply). That said, having a main breaker in the subpanel is also acceptable.
