There are numerous barriers; some more effective and safe than others. Short answer is 3 types; a mask, a non-rebreather mask, and a BVM. The older microshield and other types without a 1-way valve should no longer be used. At least, you want a CPR mask that has a 1-way valve. The next better would be the CPR mask with the O2 connection (and1-way valve). As you get more into the clinical setting, a non-rebreather and BVM would be the other types.

You covered the inlet valve with your hand, breathed in, took your hand away from the valve, and it's still sucked in? That means no air is getting in. Take the mask off and remove the inlet valve cover. See if somehow the inlet valve got stuck. If that's not it, change the filter. The only way air gets into a serviceable pro mask is through the filter, and if air isn't getting into the face piece that means it's either not getting through the inlet valve or it's not getting through the filter.

Yes, respiration is only given artificially by CPR. Respirations can be given via a mask, bag-valve mask, or mouth-to-mouth (not recommended).
Breathing is required for CPR. You can use a breathing barrier such as a mask; or use a bag valve mask for the breaths. Mouth to mouth, per se, is not recommended.
You "clear" the mask by blowing into it before "sealing" the mask by covering the inlet valve and breathing in. If there is chemical agent in the area when you don the mask, breathing in before clearing it will give you a lungful of deadly agent.
