50 mg total: You can take a total of 50 mg up to every 4 hours. I've never heard of extra strength Benadryl (diphenhydramine) (they do make a 50 mg tablet, but i've always seen it behind the counter at a pharmacy). All the over-the-counter strengths i've ever seen are 25 mg, so you can take 2 of those.

Can I take 4 benadryl (diphenhydramine) at one time?

Not recommended: that is above the usual dose and will likely produce significant sleepiness. Even one might be a problem with driving. Furthermore, it is very unlikely to produce more benefit than the recommended dose (1, at most 2).
