Is every lumia getting windows phone 10 upgrade?

[Priyanka Goswami]

If yes, then by when?

 

[mjrtoo]

No one knows

 

[Harrie-S]

Please read the article in WC it's all in there.
If your carrier does not approve you do not get it.
And you get it if it's released and when that is is not known.

probably in Q2 and for the wider rollout in Q3-Q4 (just a hunch the release timings may vary)

Probaly yes, but not all features from windows 10 are for all models.
