The answer depends on whether you want to know in the common sense or in the modern scientific sense. The phrasing of the question suggests you want to know in the common sense, but the choice of the `phylogenetics` tag indicates you want a scientific answer.
In modern biology, the term _lobe-finned fish_ would be formally taken as (an imprecise) convenient term for the clade _Sarcopterygii_. Presuming you are not an alien or computer but are human, yes, you are a lobe-finned fish (a member of the class _Sarcopterygii_ ).
In the common sense, no, you are not a fish, lobe-finned or otherwise. This would also be the answer under the old tradition of zoological taxonomy), which was based on taximetrics (measurement of an organism's form) rather on the modern phylogenetic (evolutionary relationship) basis for biological taxonomy.
