Just a simple question. I am goin' to buy new tuners to a Telecaster. And the question is, will I need the string trees if I have different post-lenghts like this?

Empty tankard! Empty Tankard!
You might do - My american Tele has staggered post heights as standard, but there is still a string tree on B & E.
If the posts are staggered a lot (like sperzels are) then there's zero need.

You CAN play anything with anything....but some guitars sound right for some things, and not for others. Single coils sound retarded for metal, though those who are apeshit about harpsichord probably beg to differ.
But it will depend on how it turns out when you install them. String trees, while annoying and many time unsightly, serve an important purpose.

As long as you can hold the angle coming off of the nut, it should be fine without them.
All my photobucket pics are dead so no links to my guitar build threads.
