We've already got one star very close to us. It's called the 'sun' and is only about 96-million miles away. There are three other stars (..the Alpha Centauri system..) that's less than 5 light years away. At distances of 5 light years or so other stars aren't going to affect Earth hardly at all except for the very tiny gravitational tug they'd exert on us plus a tiny bit more starlight at night.

If the other stars in the galaxy were closer to earth, then yeah, life still would have developed.
As far as we know, other stars had basically nothing to do with our environment and the development of life. And the radiation or particles that would reach us from 5 light years away is so nearly immeasurably small that it wouldn't have had any affect on us anyway.
Anyway, alpha centauri is 4.25 light years away.
We probably would have been fine if the nearest star was only TWO light years away.

the nearest star., other than our own sun, is andromeda. it's about five light years from earth.
as for life developing if stars were nearer to earth, they do not provide sufficient energy, heat and light to do anything more than provide an extremely low light level when the sun is on the other side of the planet.
the star would have to be within a few million miles, depending on the intensity and size, to even support any developement of life.
so to answer your question, in all probability, if the stars were nearer, within five light years, there could be no known life which could develope.

There is no way to really tell but the chances are that it wouldn't. Take Venus for example. It is much closer to the sun and no life can exist there. It is thought that Venus was probably like Earth early on but it was so close to the sun that the seas boiled away and all of the CO2 remained in the atmosphere creating a runaway greenhouse effect.

Probably. Certainly the stars could be a little nearer with no problems, but if they get too close then there is a collision danger. OK, not really a collision, but gravitational disturbance of the orbits of the planets. That would doom any life.

Of course. There are stars a little over 4 light years away.

stars are different like a interpretation of 5 light years.

Yes because the closet star to us is 4.25 light years away and we developed just fine.

yes
it shouldn't make a difference,
just a somewhat brighter night sky would be all.
5 light years is a long way away, they wouldn't really affect our solar system.

Life did not 'develop' on earth at all. Nor did it evolve.
Life was created.
