Spiriva HandiHaler - don't Sprivia,ProAir and Symbicort all relax lung muscles to open airways?

Sorry this question was not answered earlier for you.
Yes, they all help to open the airways and make breathing easier but they work in different ways and at different rates.

Spiriva (tiotropium) is an anticholinergic agent. It works by enlarging the airways to allow easier breathing. It is used to prevent bronchospasm in people with bronchitis, emphysema, or COPD (chronic obstructive pulmonary disease). Spiriva should not be used to treat a bronchospasm attack that has already begun. It will not work fast enough to reverse your symptoms.

Pro Air (Albuterol) is a bronchodilator that relaxes muscles in the airways and increases air flow to the lungs. Albuterol inhalation is used to treat or prevent bronchospasm in people with reversible obstructive airway disease. Its effects are almost immediate.

Symbicort contains a combination of budesonide and formoterol. Budesonide is a steroid that reduces inflammation in the body. Formoterol is a bronchodilator that relaxes muscles in the airways to improve breathing. Symbicort is used to prevent bronchospasm in people with asthma or chronic obstructive pulmonary disease. It should not be used to treat an acute attack as it will not work fast enough.
