In TeX I can define, say

def1#1 is #2.{#1 & is & #2.\}

and

def2#1 has #2.{#1 & has & #2.\}

with an easy usage:
1 Jim Jones is a fictional character.
and
2 Tim Smith has two brothers.

This gives three columns of a tabular: Jim Jones, is, a fictional character. Similarly in the second case.

Can I write a definition depending on, in this case, is/has so I can write

3 Jim Jones is a fictional character.
and
3 Tim Smith has two brothers.

obtaing the previous results?

Solutions using Lua or expl3 are OK, but I hope that a pure TeX one is also possible.

  At the TeX level for any def you can have only one parameter text (the #1 is #2. and #1 has #2. in your 1 and 2 respectively).

A listofitems approach. Also, listofitems is available in Plain TeX.

documentclass{article}

usepackage{listofitems}

defvariant#1.{%

  setsepchar{is||has}%

  greadlist*varinput{#1}

  varinput[1] & varinputsep[1] & varinput[2].

}

begin{document}

begin{tabular}{|c|c|c|}

variant Jim Jones is a fictional character.\

variant Tim Smith has two brothers.

end{tabular}

end{document}

Similarly done in plain TeX

input listofitems

defvariant#1.{%

  setsepchar{is||has}%

  greadlist*varinput{#1}

  varinput[1] & varinputsep[1] & varinput[2].

}

variant Jim Jones is a fictional character.



variant Tim Smith has two brothers.

  @marmot I am not sure what you mean by "teach" in this context. However, look also at my tabstackengine package, which uses listofitems for parsing. It can digest matrices and remember all the cell content for future use.

  @PrzemysławScherwentke listofitems was developed in response to my ill-fated ctan.org/pkg/getargs getargs package. It was a great idea, but just didn't do what needed to be done. Christian T. took that idea and turned it into listofitems.
