Answer 2

I haven't seen anything stating Titus only had 4 legions. However, I do know that Vespasian was also sent by Nero to quell the the rebellion and assist Titus. He had a few legions at his disposal too. I'm sure if you add up the legions between Titus and Vespasian, they will equal to around 60,000 men.
