Distance between coordinates

I'm trying to calculate the distance between coordinates, the data to be compared comes from an sql query and a geojson.

The query data are points that correspond to properties while the json data are vias.

I need to take the first point and calculate the distance to the nearest road, so on with all the points of the query within a radius of 20 KM, if you do not find anything in that radius the exit is' There are no roads nearby '.

I managed to get to read the data of the query and I am stopped when reading the json and calculate the distances in that radius.

import geopandas as geo
import pyodbc

cnn = pyodbc.connect('Driver={SQL Server};Server=****;Database=****;uid=****;pwd=****')

sqlcmd = ("Select lng, lat from inmuebles \
           inner join InmuebleDivisionPolitica b on a.idInmueble = b.idInmueble \
           inner join DivisionPolitica c on c.idDivisionPolitica = b.idDivisionPolitica \
           inner join Direccion d on d.idDivisionPolitica = c.idDivisionPolitica where d.geom is not null")

cursorConsulta = cnn.cursor()
cursorConsulta.execute(sqlcmd)

sh = geo.read_file('C:\Ferrocariles\ViasServicioPasajerosActivos.shp')

with open('C:\Ferrocariles\ViasServicioPasajerosActivos.geojson', 'w') as f:
    f.write(sh.to_json())

for r in cursorConsulta:

    latOrigen = str(r[1])
    lngOrigen = str(r[0])

the geojson data by way of example are the following
