Can amoxicillin help with walking pneumonia?

Not really: The organism mycoplasma is not sensitive to amoxicillin.These organisms are resistant to the effects of penicillins and other beta-lactam antibiotics, which act by disrupting the bacterial cell wall. Mycoplasma does not have this type of cell wall. Antibiotics with activity against these organisms include certain macrolides (erythromycin, azithromycin, clarithromycin), .

Depends: It depends on the cause of the pneumonia. A penicillin sensitive strain of s. Pneumoniae could be effectively treated with amoxicillin. You list "atypical pneumonia" which is caused by legionella, mycoplasma, chlamydophilia, q fever etc. All of which are resistant to amoxicillin.

Probably not: Walking pneumonia is not an actual clinical term. It generally means someone who has an infection in the lungs that is not severe enough to leave them bedridden during their illness. Many cases of pneumonia are caused by viruses, which do not respond to any antibiotics. Antibiotics for bacterial pneumonias depend on where patient contracted it, age, severity, etc. Amox is not a recommended tx.
