Dear Mawlana I got question which I for years I would like to know but afraid if this is not appropriate.
1. Would like to know if Nabi Khidir is mention in hadiths and has Rasulallah SAW met him
2. Is Nabi Khidir still alive, if yes what is his dawah now
3. Is there an easy way to meet him
I kiss your blessed hand
It is not mentioned in hadiths that Sayyidina al-Khidr (a) outwardly met the Holy Prophet, upon them blessings and peace, but this does not mean he never met him.
As for the second question, all the Awliya answered yes, and his daawah is to support them and strengthen them, and seeing him is reserved for them in the context of certain spiritual duties, but Allah knows best.
