A beginner asking for SERIOUS help!

[Dangerboy121]

This is my first post here, i was attracted to this forum because i recently decided to buy my first ball python.

Now, i have some few questions:
1 i want to buy a couple of ball pythons, can i put them in the same terrarium?

2 what are the necessary stuff i have to put in the terrarium? Especially the lighting and stuff, because i have no idea about the heat and temp, keep in mind that i am living in the miiddle east,UAE to be specific.

3 do i have to buy an incubator for eggs?

4 i know this question doesnot belong here , but i hope someone can help
I was planning to buy my couple from BHB located in the US, so i just wanted to ask, if i sent the snakes to my friend's house, and he send them back to me here, will the snakes stay alive this whole time ?
