This is not the correct meaning.... Mna-kuja It's a positive to - to come so it mean are you coming
"wote" is all for the -m/wa class and is not in the original. I think the only reason to use "all" would be to clarify that it's you plural, since English has no plural/singular "you." It would be nice if there was a standard way for us to write it in the course, for example "You (pl)" or "you all."
That is the command form singular (ninyi njooni plural), telling someone to come. "you come" and "you are coming" in English are both statements, which would both be translated "Unakuja" for singular or "Mnakuja" for plural.
