I have a basenji but its tail is not curled and its size is long as compared to the tail of others tell me something about that

Tails vary, some don't curl. If you can either put a link to online pictures, or click the icon (B I ........ triangle with arrow, final one Up Arrow) on the far right below the thread title to upload directly.

@usman-dangia When my Girl used to sleep her tail flopped out and was not curley. These dogs have a 'Square' Conformation and if yours has that too I would not worry about the Tail.

I’m trying to figure out if my baby girl is a basenji as well..unfortunately all pictures I choose to upload says too large..I have edited it to make it smaller but still won’t upload..hoping this recent shot went through..she doesn’t shed at all..she has pinkish color near her nose

In that shot, she looks like a basenji.
I'll happily decrease photo size if you want to send them to me.
